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...
