CVE-2026-53049 Details
Description
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().
A vulnerability in the Linux kernel's GFS2 file system log handling has been addressed. The issue arose because the function 'gfs2_logd()' called several log flushing functions without holding the necessary lock to prevent concurrent transactions, potentially leading to inconsistencies. The vulnerability has been fixed by introducing a non-locking log flush function and ensuring that the appropriate lock is held during log flushing operations.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for updating the kernel can be found in the official Linux kernel documentation.
