CVE-2026-53049

In the Linux kernel, the following vulnerability has been resolved: gfs2: add some missing log locking Function gfs2logd calls the log flushing functions gfs2ail1start, gfs2ail1wait, and gfs2ail1empty without holding sdp-sdlogflushlock, but these functions require exclusion against concurrent...

CVE-2026-53049 gfs2: add some missing log locking

In the Linux kernel, the following vulnerability has been resolved: gfs2: add some missing log locking Function gfs2logd calls the log flushing functions gfs2ail1start, gfs2ail1wait, and gfs2ail1empty without holding sdp-sdlogflushlock, but these functions require exclusion against concurrent...

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...

kernel: gfs2: Fix NULL pointer dereference in gfs2_log_flush

A flaw was found in the Linux kernel's GFS2 Global File System 2 file system. A race condition between unmounting the file system and concurrent lock processing can cause a NULL pointer dereference during log flushing. A local user could exploit this vulnerability to trigger a system crash,...

CVE-2024-42079

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix NULL pointer dereference in gfs2logflush In gfs2jindexfree, set sdp-sdjdesc to NULL under the log flush lock to provide exclusion against gfs2logflush. In gfs2logflush, check if sdp-sdjdesc is non-NULL before...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from setting sdp-sdjdesc to NULL under log flush lock in the gfs2jindexfree function to provide exclusion from th...
