A flaw was found in the Linux kernel’s SCSI driver component qla2xxx (used with FCP-2 devices). When the terminate_rport_io() function is invoked , the driver may exit cleanup before all outstanding I/O operations have returned.

A vulnerability has been identified in the Linux kernel's Network File System (NFS) daemon that could allow for a Denial of Service and in worst case scenario Arbitrary Code Execution. This Use-After-Free flaw arises from a race condition when the kernel handles the confirmation of an NFS client identifier. If an NFS client is expiring while this confirmation is in progress, the system can attempt to use memory that is no longer allocated.

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Validate UAC3 cluster segment descriptors UAC3 class segment descriptors need to be verified whether their sizes match with the declared lengths and whether they fit with the allocated buffer sizes, too. Otherwise malicious firmware may lead to the unexpected OOB accesses.

A flaw was found in the TCP subsystem in tcp_disconnect of the Linux kernel.The server-side TCP Fast Open socket was reused as a new client before the TFO socket completes, leading to an information leak.
7.6 (High)

The system must be rebooted for this update to take effect.
https://access.redhat.com/errata/RHSA-2025:23463
A flaw was found in the Linux kernel. A local attacker with low privileges could exploit a memory corruption vulnerability, specifically a use-after-free and double-free, within the TCP Fast Open (TFO) socket processing. This occurs when a listener is closed while a TFO socket is being processed in `tcp_conn_request()`. Successful exploitation could lead to a kernel panic, resulting in a Denial of Service (DoS), or potentially allow the attacker to execute arbitrary code with elevated privileges.

Remote code execution is highly unlikely \u2014 the flaw manifests as OOB reads / length miscalculations (leading to OOPS/panic or DoS), not as a controllable arbitrary-write or instruction pointer corruption, so an attacker cannot reliably gain code execution from this bug.\nThis issue only affects systems running the mwifiex driver; if the system does not use Marvell\u2019s mwifiex module there is no exposure.",

"text": "A flaw in mlx5_ib_get_hw_stats() allowed port_num=0 (device-level query) to propagate down the stack, where code paths assumed port_num \u003e= 1, leading to a NULL-pointer dereference and kernel oops during stats collection or device registration. The fix normalizes device queries by forcing port_num=1 before accessing per-port data and removes an unused variable. Exploitation requires local, highly privileged access to the RDMA device stack (e.g., devlink/IB admin), and impact is limited to local DoS.",

An attacker sending SCTP traffic can trigger incorrect processing and potentially cause a kernel denial of service on the target under specific RX conditions.\nStream Control Transmission Protocol (SCTP) is a transport-layer protocol (like TCP or UDP) primarily used in telecom signaling and some specialized applications. On most Linux systems it is disabled by default, and remote connectivity is only possible if SCTP support is enabled and listening services are configured (commonly using the IANA-assigned port 2905/tcp for M3UA or other protocol-specific ports). Therefore, the vulnerability is only exploitable when SCTP is enabled and reachable on the target system.\nAlthough KMSAN reports this issue as use of uninitialized memory (which deterministically crashes with KMSAN enabled), on production kernels the impact is still availability-related.",
