Medium [CVE-2026-53364] Fix memory leak in hci_le_big_terminate
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: Fix memory leak in hci_le_big_terminate() hci_le_big_terminate() allocates iso_list_data via kzalloc_obj but returns 0 without freeing it when neither pa_sync_term nor big_sync_term flags are set after evaluating the PA and BIG sync connection state. This early-return path was introduced when hci_le_big_terminate() was refactored to take struct hci_conn instead of raw u8 parameters, adding PA/BIG flag evaluation logic. The existing kfree() on hci_cmd_sync_queue failure does not cover this path. A flaw was found in the Linux kernel's Bluetooth Host Controller Interface (HCI) connection handling. The `hci_le_big_terminate()` function, which is responsible for terminating Bluetooth connections, allocates memory but fails to free it under specific conditions when certain flags are not set. This memory leak could lead to resource exhaustion, potentially resulting in a denial of service (DoS). 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).

High [CVE-2026-57215] Persistent foreign bindings allow unauthorized message routing
RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ allows foreign bindings to amq.rabbitmq.reply-to destinations because volatile direct-reply-to queues can be accepted at bind and route time but are missing from Khepri-backed deletion checks, leaving persistent route entries after unbind. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6. This occurs because temporary queues are not properly removed, leaving behind active routing entries. This can lead to unauthorized message routing and potential exposure of sensitive information. Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-459. Affected Red Hat products: Red Hat Hardened Images. Red Hat lists Red Hat OpenStack Platform 16.2; Red Hat OpenStack Platform 17.1; Red Hat OpenStack Platform 18.0 as not affected.

High [CVE-2026-57156] Arbitrary code execution or denial of service via integer overflow in RDP message processing
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0. A remote attacker, acting as a malicious Remote Desktop Protocol (RDP) peer, could exploit an integer overflow vulnerability. This overflow occurs when the client processes a specially crafted RDP message, leading to the allocation of an undersized memory buffer. Consequently, the client attempts to write data beyond the boundaries of this buffer, which can result in arbitrary code execution or a denial of service. 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-787. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: freerdp.
High [CVE-2026-55827] Remote code execution via heap out-of-bounds write in RemoteFX decoding
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.1, FreeRDP clients launched with the non-default /cache:codec:rfx option pass desktop stride and height to RemoteFX decoding for Cache Bitmap V3 data while allocating bitmap->data only for the smaller DstWidth and DstHeight in gdi_Bitmap_Decompress, allowing a malicious RDP server to trigger a heap out-of-bounds write with attacker-controlled offset and content. This issue is fixed in version 3.27.1. A flaw was found in FreeRDP. This can lead to arbitrary code execution on the client system. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-787. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat lists Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat fixing advisory: RHSA-2026:50747, RHSA-2026:54667. Affected products named by the advisory: Red Hat package: freerdp.
High [CVE-2026-53450] Localhost services exposed via IPv4-mapped IPv6 address bypass
Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.0, coturn rejects loopback peers by default unless allow-loopback-peers is enabled, but the default loopback guard can be bypassed by using the IPv4-mapped IPv6 peer address::ffff:127.0.0.1 in a TURN XOR-PEER-ADDRESS attribute. ioa_addr_is_loopback checks for the literal IPv6 loopback shape before IPv4-mapped IPv6 handling, so good_peer_addr does not apply the default loopback rejection and an authenticated TURN client can expose services bound only to localhost on the coturn host through TURN relay traffic. This issue is fixed in version 4.13.0. This could lead to unauthorized access to internal services. This flaw affects the community-maintained coturn TURN/STUN server as shipped in Fedora and EPEL. Red Hat does not ship coturn in any core Red Hat product. Fedora and EPEL currently ship coturn 4.14.0, which already includes the fix released in 4.13.0, so the shipped builds are not vulnerable to this loopback-protection bypass via IPv4-mapped IPv6 addresses. Red Hat severity: Important — CVSS 7.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L). Weakness: CWE-289.
