High [CVE-2026-68267] Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists

In the Linux kernel, the following vulnerability has been resolved: drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists Unconditionally whitelisting OA registers is a security violation. Set RING_FORCE_TO_NONPRIV_DENY bit in OA nonpriv slots, so that OA registers don't get whitelisted by default after probe, gt reset, resume and engine reset. (cherry picked from commit 90511bdcfda97211c01f1d945d4ea616578d8fca) This vulnerability arises from the unconditional whitelisting of Output/Availability (OA) registers, which is a security violation. This improper whitelisting could allow a local attacker to gain unauthorized access to privileged OA registers, potentially leading to a security bypass or information disclosure. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-1188. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux for NVIDIA 26. Red Hat lists Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat OpenShift Container Platform 4 as not affected. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: kernel-rt.

High [CVE-2026-68158] Fix multiplication overflow in decode_new_up_state_weight

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix multiplication overflow in decode_new_up_state_weight() If a message of type CEPH_MSG_OSD_MAP contains a (maliciously) corrupted osdmap, out-of-bounds memory accesses may occur in decode_new_up_state_weight(). This happens because the bounds check for the new_state part is based on calculating its length depending on a len value read from the incoming message. This calculation may overflow leading to an incorrect bounds check. Subsequently, out-of-bounds reads may occur when decoding this part. This patch switches the multiplication to use check_mul_overflow() to abort processing the osdmap if an overflow occurred. Therefore, osdmaps/messages containing large values for len that result in a multiplication overflow are treated as invalid. [ idryomov: rename new_state_len -> new_state_item_size, formatting ] A remote attacker could send a maliciously crafted `CEPH_MSG_OSD_MAP` message, leading to a multiplication overflow in the `decode_new_up_state_weight()` function. This could potentially lead to information disclosure or system instability. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-125.

High [CVE-2026-68266] Hold a dma-buf reference for imported BOs

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Hold a dma-buf reference for imported BOs An imported dma-buf BO is created as a ttm_bo_type_sg BO whose reservation object is the exporter's dma_buf->resv. The importer, however, only takes a dma-buf reference after a successful dma_buf_dynamic_attach(). Until then nothing keeps the exporter alive, so if the exporter is freed while the BO still references its resv, a later access to that resv is a use-after-free: Oops: general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b6b9c Workqueue: ttm ttm_bo_delayed_delete [ttm] RIP: 0010:mutex_can_spin_on_owner+0x3f/0xc0 This can be reached on two paths: - dma_buf_dynamic_attach() fails, or - ttm_bo_init_reserved() fails during BO creation. In both cases the BO already has bo->base.resv pointing at the exporter resv, and sg BOs are always torn down via ttm_bo_delayed_delete(), which locks bo->base.resv asynchronously - potentially after the exporter has been freed. Take the dma-buf reference in xe_bo_init_locked(), before ttm_bo_init_reserved(), so it also covers a creation failure there, and release it in xe_ttm_bo_destroy().

High [CVE-2026-68245] fix lifetime issue of amdgpu_vm_get_task_info_pasid

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix lifetime issue of amdgpu_vm_get_task_info_pasid() The vm pointer returned from amdgpu_vm_get_vm_from_pasid() is only valid while the lock is still being held. Once xa_unlock_irqrestore is called and returned, the pointer is no longer under lock and is subject to modification. Since, the caller still dereferences vm->task_info in amdgpu_vm_get_task_info_vm() after the lock is removed, this causes a use after unlock problem. Remove the lifetime issue present in amdgpu_vm_get_task_info_pasid() through removing the amdgpu_vm_get_vm_from_pasid() function from amdgpu_vm.c and making the relevant code inline to hold the lock while it is still in use. (cherry picked from commit 9d01579f3f868b333acc901815972685989092c7) A use-after-unlock vulnerability exists where a virtual machine (VM) pointer is dereferenced after its protective lock has been released. This allows the pointer to be modified, potentially leading to memory corruption. An attacker could exploit this to cause a denial of service or achieve privilege escalation. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825.

High [CVE-2026-68273] Fix context pstate override handling

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix context pstate override handling There are several problems in the context pstate handling code. The most serious ones are potential use-after-free and NULL pointer dereferences at context initialization time. Both are due amdgpu_ctx_init() not holding the adev->pm.stable_pstate_ctx_lock, which is otherwise used from both sysfs and the context code itself for modifying and clearing the stored context pointer. Second issue is that context fini can trample over the pstate configuration set via sysfs. This is due the restore state (ctx->stable_pstate) being saved at context init time, and not if, or when the context actually changes the pstate. As the context exits it will therefore incorrectly restore to what was set before the sysfs override was requested. The simplest fix is to drastically simplify how the state is tracked, by clearly defining the points at which pstate ownership is taken and released, and to handle all transitions under the correct lock. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux for NVIDIA 26; and 1 more.

High [CVE-2026-68169] fix use-after-free in get_local_id

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: userspace: fix use-after-free in get_local_id In mptcp_pm_userspace_get_local_id(), the address entry is looked up under spinlock, but its id is read after dropping the lock. A concurrent deletion can free the entry between the unlock and the read, leading to UAF. The race window is narrow. It was reproduced only with a locally constructed stress test that repeatedly overlaps an MP_JOIN SYN with a MPTCP_PM_CMD_SUBFLOW_DESTROY request. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat package: kernel-rt.

High [CVE-2026-68427] Fix use-after-free in host1x_bo_clear_cached_mappings

In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Fix use-after-free in host1x_bo_clear_cached_mappings __host1x_bo_unpin() drops the last reference to the mapping and frees it, so we can't dereference mapping afterwards. The cache itself outlives the mapping, so use the cache local variable instead. The `__host1x_bo_unpin()` function incorrectly dereferences a memory mapping after it has been freed, leading to a use-after-free vulnerability. This issue could allow a local attacker to cause memory corruption, potentially leading to a system crash (Denial of Service) or, in more severe scenarios, arbitrary code execution. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9.

High [CVE-2026-68123] fix GSO userspace truncation underflow

In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix GSO userspace truncation underflow OVS_ACTION_ATTR_TRUNC currently stores a delta from the original skb length in OVS_CB(skb)->cutlen. When a later userspace action segments a GSO skb, queue_gso_packets() reuses that delta for each smaller segment. A segment can then reach queue_userspace_packet() with cutlen greater than skb->len, underflowing the length passed to skb_zerocopy(). Store the maximum preserved length instead and bound each consumer against the current skb length. Use U32_MAX as the no-truncation sentinel so the value remains valid if skb geometry changes before a consumer handles it. A flaw was found in the Open vSwitch component of the Linux kernel. This vulnerability arises from an underflow condition when handling Generic Segmentation Offload (GSO) packets in userspace. A length calculation error can lead to a buffer underflow when data is processed by the `skb_zerocopy()` function. This issue could result in memory corruption, potentially leading to a denial of service or other unpredictable system behavior. Red Hat severity: Important — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-787.

High [CVE-2026-68264] Reset current_op in xe_pt_update_ops_init

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pt: Reset current_op in xe_pt_update_ops_init() xe_pt_update_ops_init() fails to reset current_op to 0. On the vm_bind path, ops_execute() calls xe_pt_update_ops_prepare() inside the xe_validation_guard() / drm_exec_until_all_locked() loop. When that loop retries due to lock contention or OOM eviction (drm_exec_retry_on_contention() / xe_validation_retry_on_oom()), xe_pt_update_ops_prepare() runs again on the same vops, and each call to bind_op_prepare() increments current_op without resetting it. After N retries current_op exceeds the array size allocated by xe_vma_ops_alloc(), causing an out-of-bounds write into SLUB-poisoned memory and a subsequent UAF crash in xe_migrate_update_pgtables_cpu() when reading the corrupted pt_op->bind. Also reset needs_svm_lock and needs_invalidation which are derived in the same prepare pass and would otherwise cause wrong migrate ops selection and redundant TLB invalidation on retry. Fix this by resetting current_op, needs_svm_lock and needs_invalidation in xe_pt_update_ops_init(). v2 (Matt): - Add details in commit message. - Add Fixes tag and Cc to stable@vger.kernel.org (cherry picked from commit 046045543e530605c441063535e7dca0075369a6) During certain memory management operations, an internal counter is not properly reset.

High [CVE-2026-68391] hold reference for hci_conn in mgmt_pending_cmds

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Use of hci_conn in hci_sync callbacks also needs to hold refcount to avoid UAF. Take appropriate locks for hci_conn lookups, and take refcount for hci_conn pointers stored in mgmt_pending_cmd so that the pointer stays valid. When accessing conn->state, ensure hdev->lock is held to avoid data race. A flaw was found in the Linux kernel's Bluetooth management component. This vulnerability involves a Use-After-Free (UAF) condition, a type of memory corruption where the system attempts to use memory after it has been freed. This can occur due to improper handling of `hci_conn` pointers, potentially leading to arbitrary code execution or a denial of service. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-911. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9.

In the Linux kernel, the following vulnerability has been resolved: usb: core: sysfs: add lock to bos_descriptors_read() Add a lock to the function bos_descriptors_read(). This function accesses udev->bos, which could be simultaneously freed in usb_reset_and_verify_device(), a function that is commonly called in drivers all over the kernel. A missing synchronization mechanism in the `bos_descriptors_read()` function allows for a use-after-free vulnerability. This occurs when the `udev->bos` object is accessed while it is simultaneously being freed, potentially leading to a system crash (denial of service) or, in some cases, arbitrary code execution. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825.

Protect queues cleanup and WARN traversal by device lock there to avoid the concurrent access problems. Move WARN traversal before mei_dev_bus_put(bus). This file uses bus variable name for mei_device, adjust code of mei_cl_bus_dev_release() to use bus variable too. This flaw, caused by improper synchronization during cleanup, could lead to memory corruption and system instability.

Medium [CVE-2026-68428] Fix use-after-free on vendor module reload

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Fix use-after-free on vendor module reload mmu_destroy_caches() destroys pte_list_desc_cache and mmu_page_header_cache, but leaves both pointers unchanged. The pointers live in kvm.ko, and therefore survive when a vendor module is unloaded while kvm.ko remains loaded. If creation of pte_list_desc_cache fails during a subsequent vendor module load, its assignment sets pte_list_desc_cache to NULL and the error path calls mmu_destroy_caches(). mmu_page_header_cache still points to the cache destroyed during the preceding vendor module unload. Passing that stale pointer to kmem_cache_destroy() causes a slab use-after-free. Reproduce the issue on a v7.1.3 kernel with CONFIG_KASAN=y, CONFIG_KASAN_GENERIC=y, CONFIG_KVM=m, and CONFIG_KVM_INTEL=m. A one-shot test hook forces pte_list_desc_cache to NULL on the second invocation of kvm_mmu_vendor_module_init(): 1. Load kvm.ko and kvm-intel.ko, creating both caches. 2. Unload only kvm_intel, leaving kvm.ko loaded. 3. Reload kvm_intel and force initialization through the -ENOMEM path. KASAN reports: BUG: KASAN: slab-use-after-free in kvm_mmu_vendor_module_init+0x5b/0x170 [kvm]... kmem_cache_destroy+0x21/0x1d0 kvm_mmu_vendor_module_init+0x5b/0x170 [kvm]...

Medium [CVE-2026-68425] Drop unmatched RMPP responses before reassembly

In the Linux kernel, the following vulnerability has been resolved: IB/mad: Drop unmatched RMPP responses before reassembly Kernel-handled RMPP receive processing starts reassembly for active DATA responses before the response is matched to an outstanding send. The normal match happens later, after ib_process_rmpp_recv_wc() has either assembled a complete message or consumed the segment. That ordering lets an unsolicited response that routes to a kernel RMPP agent by the high TID bits allocate or extend RMPP receive state before the full TID and source address are checked against a real request. A reordered burst can therefore reach the receive-side insertion path even though the response would not match any send. The matcher already checks the full TID, management class and source address/GID against the agent wait, backlog and in-flight send lists. If there is no match, drop the response without creating RMPP state. This leaves the RMPP window behavior unchanged and only rejects responses that have no corresponding request. A flaw was found in the Linux kernel's InfiniBand (IB) Management Datagram (mad) component. A remote attacker could exploit this vulnerability by sending unsolicited Reliable Multicast Packet Protocol (RMPP) responses.

Medium [CVE-2026-68422] fix root leak if its reloc root is unexpected in merge_reloc_roots

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix root leak if its reloc root is unexpected in merge_reloc_roots() If we have an unexpected reloc_root for our root, we jump to the out label but never drop the reference we obtained for root, resulting in a leak. Add a missing btrfs_put_root() call. A flaw was found in the btrfs filesystem component of the Linux kernel. An unexpected relocation root in the `merge_reloc_roots()` function can lead to a resource leak. This occurs because a reference to the root is not properly released, potentially causing system instability or a denial of service due to resource exhaustion. This issue affects systems using the Btrfs file system during balance/relocation operations. If merge_reloc_roots() encounters an unexpected relocation root, it exits without releasing a reference on the root structure, leaking memory. Over time this can contribute to resource exhaustion on affected workloads. Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-772.

Medium [CVE-2026-68421] Don't warn on core-sched forced idle in put_prev_task_scx

In the Linux kernel, the following vulnerability has been resolved: sched_ext: Don't warn on core-sched forced idle in put_prev_task_scx() put_prev_task_scx() warns when a runnable task drops to a lower sched_class without SCX_OPS_ENQ_LAST, on the assumption that balance_one() would have kept it running. Core scheduling breaks that: a forced-idle SMT sibling reschedules through the core_pick fast path in pick_next_task(), which skips pick_task_scx() and thus balance_one(), so a runnable task can drop to idle with ENQ_LAST unset. Gate the warning on sched_cpu_cookie_match(): a cookie mismatch means core scheduling forced the idle, while a match (or core scheduling off) still catches a genuine missing-ENQ_LAST drop. The `put_prev_task_scx()` function incorrectly issues a warning when a runnable task transitions to an idle state due to core scheduling. This occurs because the core scheduling mechanism bypasses certain checks, leading to a misleading warning. This issue affects sched_ext (BPF scheduler). Requires CONFIG_SCHED_CLASS_EXT. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-1288. Affected Red Hat products: Red Hat Enterprise Linux for NVIDIA 26.

Medium [CVE-2026-68418] Prevent user-triggered null deref on QP create

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp->iwpbl if the user-provided req.user_wqe_bufs field was non-zero. The problem is that iwqp->iwpbl is unconditionally dereferenced later on in irdma_setup_virt_qp. The end result is that a user could send a zero user_wqe_bufs value and trigger a null ptr deref. Fix this by unconditionally calling irdma_get_pbl and bailing if it fails, similar to the CQ and SRQ paths. A local user could exploit this vulnerability by providing a zero value for `user_wqe_bufs` during the creation of a Queue Pair (QP). This action leads to a null pointer dereference, which can cause the system to crash, resulting in a Denial of Service (DoS). This issue affects systems using the Intel RDMA (irdma) driver. A local user creating a queue pair with user_wqe_bufs set to zero can trigger a NULL pointer dereference because iwpbl is not allocated but is later dereferenced unconditionally. Systems without irdma/RDMA userspace access are not affected. Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-476.

Medium [CVE-2026-68417] publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siw_create_qp() currently calls siw_qp_add() before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being constructed. The `siw_create_qp()` function prematurely publishes a Queue Pair (QP) before its complete initialization. This allows a Queue Pair Number (QPN) lookup to access a QP that is still under construction, potentially leading to unexpected behavior or system instability. This issue affects RDMA siw (Soft-iWARP). QP published to lookup table before initialization completes. Systems not using siw RDMA are not affected.
