CVE-2026-53049

CRITICAL · 9.8 CVSS Gepubliceerd: CWE-667

Beschrijving NL

In the Linux kernel, the following vulnerability has been resolved:

gfs2: add some missing log locking

Function gfs2_logd() calls the log flushing functions gfs2_ail1_start(),
gfs2_ail1_wait(), and gfs2_ail1_empty() without holding sdp->sd_log_flush_lock,
but these functions require exclusion against concurrent transactions. To fix that, add a non-locking __gfs2_log_flush() function. Then, in
gfs2_logd(), take sdp->sd_log_flush_lock before calling the above mentioned log
flushing functions and __gfs2_log_flush().
