Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ext4: fixed an issue where the buffer of extents was freed twice. In ext4exttrytomergeup, the path1.pbh was set to NULL after it was released. Otherwise, it might be released twice. An example of what triggers this is as...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fixed invalid buffer access for legacy rq The following crash can occur when using xdpsock in RX mode for legacy rq: the buffer is released in the XDPREDIRECT path, and then again in the driver. This fix sets a fl...

CVE-2026-46240

A flaw was found in the Linux kernel, specifically within the media: iris driver. This vulnerability, a use-after-free, occurs when a buffer is prematurely freed by sessionreleasebuf while irisreleaseinternalbuffers continues to access it. This improper handling of memory can lead to system...

CVE-2026-46240

The CVE-2026-46240 issue affects the Linux kernel iris driver. A use-after-free occurs when iris_release_internal_buffers() accesses a buffer after session_release_buf() frees it, caused by a regression from a change that destroys internal buffers after FW releases. The documented fix sets BUF_AT...

EUVD-2026-32486

In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers...

CVE-2026-43225

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix memory leak on failure path cfg80211informbssframe may return NULL on failure. In that case, the allocated buffer 'buf' is not freed and the function returns early, leading to potential memory leak. Fix th...

CVE-2026-43153

CVE-2026-43153 affects the Linux kernel’s XFS attribute handling: the function xfs_attr_leaf_hasname has an problematic calling convention that can mishandle buffers. The fix is to open-code xfs_attr_leaf_hasname in callers so each caller of xfs_attr3_leaf_read manages buffer release. The issue i...
