High [CVE-2026-12382] missing requestHeadersToRemove allows mTLS bypass via Subject header spoofing
A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed Subject header matching a legitimate client certificate DN to bypass mTLS authentication and inject arbitrary events into protected EDA event streams. This flaw affects AAP deployments that use mTLS-protected EDA external event streams. Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N). Weakness: CWE-290. Affected Red Hat products: Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Ansible Automation Platform 2.5 for RHEL 9; Red Hat Ansible Automation Platform 2.6 for RHEL 9; Red Hat Ansible Automation Platform 2.6; Red Hat Ansible Automation Platform 2.7. Red Hat fixing advisory: RHSA-2026:42078, RHSA-2026:13508, RHSA-2026:13545, RHSA-2026:42142.
High [CVE-2026-58659] Remote code execution via malicious checkpoint files
PyTorch Lightning through 2.6.5, fixed in commit d710d68, contains a remote code execution vulnerability in the _load_state function that imports and executes attacker-controlled module names from checkpoint _instantiator hyperparameters. Attackers can craft malicious checkpoint files that bypass weights_only=True protections to execute arbitrary code when LightningModule.load_from_checkpoint is called. This vulnerability allows attackers to achieve remote code execution by crafting malicious checkpoint files. The vulnerability arises from the _load_state function's ability to import and execute attacker-controlled module names from maliciously crafted checkpoint files, even when weights_only=True is enabled. Exploitation requires a local attacker to trick a user into loading a specially crafted checkpoint file. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-502. Affected Red Hat products: Red Hat AI Inference Server; Red Hat Enterprise Linux AI (RHEL AI) 3; Red Hat OpenShift AI (RHOAI). Will not fix / out of support: Red Hat AI Inference Server. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-45804] Arbitrary code execution due to trust_remote_code guard bypass
Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, Diffusers' DiffusionPipeline.from_pretrained flow can bypass the trust_remote_code guard because download() validates model_index.json and custom pipeline code before later loading from a cached folder that can change, allowing a Hub repository with custom.py pipeline code to execute through the custom pipeline flow without passing custom_pipeline or trust_remote_code=True. This issue is fixed in version 0.38.0. A remote attacker could exploit this vulnerability by crafting a malicious Hub repository with custom Python pipeline code. The `DiffusionPipeline.from_pretrained` flow can bypass the `trust_remote_code` security mechanism, allowing the execution of arbitrary code on the system when a user interacts with the malicious repository. This could lead to high impact on confidentiality, integrity, and availability of the affected system. This Important flaw in Diffusers, as used in Red Hat AI Inference Server, Red Hat OpenShift AI, and Red Hat Enterprise Linux AI, allows for arbitrary code execution. A remote attacker could exploit this by convincing a user to load a specially crafted model from a malicious Hub repository, bypassing the `trust_remote_code` safeguard. This could lead to a complete compromise of the system where the model is loaded.
High [CVE-2026-60005] Memory disclosure and denial of service in ngx_http_slice_module
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_slice_module module. When the slice directive and unnamed regex captures are configured or when a background cache update happens, unauthenticated attackers can send requests that may cause uninitialized memory access in the NGINX worker process, leading to limited disclosure of memory or a restart. There is no control plane exposure; this is a data plane issue only. Note: The ngx_http_slice_module module is not enabled by default; it's enabled with the --with-http_slice_module configuration parameter. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. Important: This vulnerability in NGINX's `ngx_http_slice_module` could lead to memory disclosure or denial of service. The impact on Red Hat products is reduced because the `ngx_http_slice_module` is not enabled by default. Exploitation requires explicit configuration of the module with the `slice` directive and unnamed regex captures, or during a background cache update, limiting exposure in typical deployments. Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H). Weakness: CWE-824. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Discovery 2; Red Hat Hardened Images; Red Hat Lightspeed proxy 1.
High [CVE-2026-42533] Arbitrary code execution via crafted HTTP requests
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. A flaw was found in NGINX. Additionally, this flaw can cause a denial-of-service (DoS) due to the NGINX worker process restarting. This vulnerability in NGINX allows a remote, unauthenticated attacker to trigger a heap buffer overflow, leading to a denial of service (Dos).
High [CVE-2022-4318 +1] Fix Bypass for CVE-2022-4318 — /etc/passwd Injection via HOME env
A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable. This Important flaw in CRI-O allows for arbitrary line injection into a container's `/etc/passwd` file. This risk is present in environments where untrusted users can influence container environment variable settings. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-134. Affected Red Hat products: Red Hat OpenShift Container Platform 4.22; Confidential Compute Attestation; Red Hat OpenShift Container Platform 4. Will not fix / out of support: Red Hat OpenShift Container Platform 4. Red Hat fixing advisory: RHSA-2026:57361.
High [CVE-2026-14251] Missing allowedNamespace check in ReconcilerHook for ClusterRole/Role cases enables potential privilege escalation and DoS
A flaw was found in the OpenShift GitOps operator. The ClusterRole reconciler does not validate resource ownership when reconciling ClusterRole objects. A namespace-scoped Argo CD instance can trigger deletion of a ClusterRole owned by a cluster-scoped Argo CD instance by crafting a name collision, resulting in a denial of service. Red Hat severity: Important — CVSS 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H). Weakness: CWE-862. Affected Red Hat products: Red Hat OpenShift GitOps. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-30623] Remote code execution via unvalidated MCP server configuration
LiteLLM 1.18.10 contains a remote code execution vulnerability in its MCP server creation functionality. The application allows users to add MCP servers via a JSON configuration specifying arbitrary command and args values. LiteLLM executes these values on the host without validation, enabling attackers to run arbitrary operating system commands. Successful exploitation may result in remote code execution with the privileges of the LiteLLM process. A flaw was found in LiteLLM. This is possible because the application's MCP server creation functionality processes JSON configurations that can include unvalidated command and argument values. Successful exploitation could lead to a complete compromise of the affected system. Per the upstream advisory, exploitation requires authentication -- it is not reachable by a fully unauthenticated attacker -- but no further privilege beyond a working API key is needed to reach the vulnerable code path. Red Hat severity: Important — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-78. Red Hat lists Exploit Intelligence; Lightspeed Core; Red Hat Ansible Automation Platform 2; Red Hat OpenShift AI (RHOAI) as not affected.
High [CVE-2026-38974] Missing SSH host key verification allows potential impersonation
Dulwich through 1.1.0 was found to be missing SSH host key verification in contrib/paramiko_vendor.py. This vulnerability allows a remote attacker to impersonate a legitimate Git server. By doing so, the attacker could potentially intercept sensitive information or execute arbitrary code on the client system during a connection. Exploitation requires user interaction, specifically connecting to a malicious Git server. Red Hat severity: Important — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-322. Affected Red Hat products: Red Hat OpenShift AI (RHOAI); Red Hat OpenShift Container Platform 4. Under investigation: Red Hat Ansible Automation Platform 2; Red Hat Enterprise Linux 7; Red Hat Satellite 6. Red Hat lists Red Hat OpenShift AI (RHOAI) as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-14957] badly formatted X.509 certificate can cause an assertion failure that crashes the daemon process
A flaw was found in Libreswan. An unauthenticated remote attacker can send a specially crafted X.509 certificate payload during an IKEv1 or IKEv2 exchange. This flaw occurs when Libreswan is operating in FIPS (Federal Information Processing Standards) mode and processing a certificate with an invalid public key, such as an RSA exponent of zero. This can trigger an assertion failure, leading to the termination of the daemon process and a denial of service. Moderate: This flaw in Libreswan, when operating in FIPS mode with certificate-based authentication, allows an unauthenticated remote attacker to trigger a denial of service. The assertion failure occurs during X.509 certificate processing with a malformed certificate, leading to the daemon crashing. This impact is limited to specific configurations where both FIPS mode and certificate-based authentication are actively utilized. It means, when Libreswan is running in FIPS mode and certificate-based authentication is in use with at least one CA certificate loaded in the Libreswan NSS database. Deployments using only Pre-Shared Key (PSK) authentication without loaded CA certificates are not affected. Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-617.
Medium [CVE-2026-56434] Heap buffer over-read allows memory modification or denial of service
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_ssi_module module. This vulnerability may exist when the Server-Side Includes (SSI), proxy_pass, and proxy_buffering off directives are configured. With this configuration, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to cause a use-after-free in the NGINX worker process. This issue may lead to limited modification of memory or a restart of the NGINX worker process. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. A vulnerability in NGINX's ngx_http_ssi_module allows an unauthenticated MITM attacker to trigger a heap buffer over-read by manipulating upstream server responses. This requires SSI, proxy_pass, and proxy_buffering off to be configured, and can result in memory modification or a Denial of Service (DoS). This Moderate severity vulnerability in NGINX affects configurations utilizing the `ngx_http_ssi_module` alongside `proxy_pass` and `proxy_buffering off`. The specific combination of directives and an active MITM position limits the overall impact. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-125.
Medium [CVE-2026-15779] pam_winbind mkhomedir chowns critical system paths without validation
A flaw was found in samba's pam_winbind. When mkhomedir is enabled, pam_winbind chowns the target account's home directory without validating the path is not a critical system directory such as /. On affected systems, accounts with / as their home directory (a common default for system accounts) can have this triggered not only by root, but by a non-root user holding a narrow sudo delegation to run commands as that account, causing ownership of / to change and resulting in severe denial of service (SSH, sudo, and package-manager failures). The change does not grant write access to / (which ships with restrictive 0555 permissions on RHEL), so the impact is availability loss rather than further privilege escalation. Red Hat Product Security rates this flaw's impact as Moderate. Exploitation requires mkhomedir to be explicitly enabled in pam_winbind.conf, a non-default option used specifically in Active Directory domain-integration deployments, and a PAM session to be opened for an account whose home directory resolves to /. While the most direct trigger is root running su to such an account, a non-root user holding a narrow sudo delegation to run a command as that account can reach the same code path. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; and 2 more.
Medium [CVE-2026-15812] access control list bypass via link ID spoofing on unencrypted dynamic links
A vulnerability was found in the internal Access Control List (ACL) subsystem of kronosnet (Version affected: <= 1.34). When the framework is explicitly configured to manage dynamic links (accepting network traffic from any IP address) without network payload encryption, the validation architecture implicitly trusts the link ID provided within incoming data packets. A remote, unauthenticated attacker can exploit this lack of validation by spoofing a legitimate link ID inside crafted network frames. This allows the attacker to fully bypass the ACL framework and inject arbitrary data packets into the application layer, potentially leading to data corruption or service instabilities. Red Hat Product Security rates this vulnerability's impact as Low. Although the vulnerability allows an unauthenticated remote attacker to completely bypass the internal ACL layer and introduce arbitrary traffic, it depends entirely on a non-production configuration. The exploit requires that kronosnet actively accept connections from any arbitrary IP (dynamic links) while simultaneously running completely unencrypted traffic. Furthermore, this issue does not affect Red Hat Enterprise Linux High Availability (RHEL HA) or any official layered products, as Red Hat configurations securely enable network encryption by default, entirely mitigating the vulnerability's attack prerequisites.
Medium [CVE-2026-15811] encryption key exposure in memory after cryptographic configuration changes
A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability. Red Hat Product Security rates this flaw's impact as Moderate. While kronosnet is a critical core networking component within the Red Hat Enterprise Linux High Availability (RHEL HA) ecosystem, exploiting this vulnerability requires a high degree of complexity. An attacker must already possess local access to the host machine and successfully pair this flaw with a distinct memory disclosure mechanism to extract the key fragments post-free(). Red Hat severity: Low — CVSS 5.8 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L). Weakness: CWE-212. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-38755] Denial of Service via heap overflow in evalcommand function
A heap overflow in the evalcommand() function (shell/ash.c) of Busybox v1.38.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted input. A flaw was found in Busybox. This can lead to the unavailability of the service. The vulnerability requires an attacker to supply specially crafted input, which typically implies existing local access or specific application interactions within the Busybox environment, thus limiting the direct exposure. 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-120. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 6. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat fixing advisory: RHSA-2026:42074. Affected products named by the advisory: Red Hat package: busybox.
Medium [CVE-2026-38752] Denial of Service via crafted AWK script
A stack overflow in the evaluate() function (editors/awk.c) of BusyBox commit 371fe9 allows attackers to cause a Denial of Service (DoS) via supplying a crafted AWK script. A flaw was found in BusyBox. A Denial of Service attack can make the affected system or application unavailable to legitimate users. An attacker could provide a specially crafted AWK script, leading to a stack overflow and making the BusyBox instance unresponsive. This vulnerability primarily affects systems where BusyBox is configured to execute untrusted AWK scripts, limiting its broader impact. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-120. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 6. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat fixing advisory: RHSA-2026:42074. Affected products named by the advisory: Red Hat package: busybox.
