Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fixed a NULL pointer dereferencing in gfs2logFlush. In gfs2jindexfree, sdp-sdjdesc was set to NULL under the log flush lock to prevent dereferencing of sdp-sdjdesc during gfs2logFlush. In gfs2logFlush, it was checked whethe...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

CVE-2026-63804

In the Linux kernel, the following vulnerability has been resolved: gfs2: fix use-after-free in gfs2qddealloc gfs2qddealloc, called as an RCU callback from gfs2qddispose, accesses the superblock object sdp through qd-qdsbd after freeing qd. It does so to decrement sdquotacount and wake up...

CVE-2026-53049

CVE-2026-53049 affects the Linux kernel GFS2 component. The root cause is that gfs2_logd() called log-flushing routines (gfs2_ail1_start(), gfs2_ail1_wait(), gfs2_ail1_empty()) without holding sdp->sd_log_flush_lock, exposing a risk of race conditions with concurrent transactions. The patch in...
