CVE-2026-40211

An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3 streams to trigger an out-of-memo...

CVE-2026-52981

CVE-2026-52981 concerns a Linux kernel issue in neigh_xmit: when called with an uninitialized neighbor table (e.g., NEIGH_ND_TABLE with IPv6 disabled), neigh_xmit can return -EAFNOSUPPORT without releasing the skb, risking a memory leak. The fix removes the remaining code path that could neither ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: pmc: Fixed a memory leak in amdpmcstbdebugfsopenv2. The function amdpmcstbdebugfsopenv2 may be called when the STB debug mechanism is enabled. When amdpmcsendcmd fails, the ‘buf’ variable needs to be released...

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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the gfs2 file system’s gfs2fillsuper function. The improper handling of this function, particular...

SUSE CVE-2026-43153

In the Linux kernel, the following vulnerability has been resolved: xfs: remove xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic, because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

In the Linux kernel, the following vulnerability has been resolved: xfs: remove xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic, because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

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...
