Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.3.0-rc1
Description
The Linux kernel contains a flaw in the fs/dax.c component related to copy-on-write (CoW) handling within the XFS filesystem. Specifically, the code fails to clear a dirty mark on an old, non-shared extent before invalidating inode pages, leading to a warning during operation. This can occur when CoW is enabled on non-shared extents to address fragmentation.
Recommendations
Update to a newer kernel version that addresses this issue.
