CVE-2026-97971

The Linux kernel is vulnerable to a race condition where legitimize_ns() takes a reference on a candidate namespace before may_list_ns() determines if the caller has permission to see it. This can lead to the __free(ns_put) cleanup dropping the last reference to a mount namespace while holding an...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dochangetype: refusal to operate on unmounted/not-of-our-mounts mounts. It is ensured that propagation settings can only be changed for mounts located within the caller’s mount namespace. This change aligns permission checks with...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: unshare: fixed the handling of unsharefs There’s an unpleasant corner case in unshare2: when CLONENEWNS is used in the flags, and current-fs hasn’t been shared at all; in that case, copymntns passes current-fs instead of a privat...

Astra Linux – Vulnerability in udisks2

A flaw was discovered in udisks2. A local attacker with an active console session can exploit insufficient authorization checking for the “as-user” option in the org.freedesktop.UDisks2.Filesystem.Mount D-Bus method. This allows the attacker to forge the “as-user” parameter, mounting file systems...

CVE-2026-74484

CVE-2026-74484 concerns the Linux kernel’s binfmt_misc feature: an entry registered with the character 'F' can cause the interpreter to pin itself, preventing proper unregistration and leading to a DoS with leaked resources (including user namespaces). The issue arises when the interpreter’s file...
