Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the XFS file system where log items may be dereferenced after push callbacks. Specifically, after the
xfsaild push item() function calls iop push(), the log item might have been freed if the AIL lock was dropped during the push process. This can occur during background inode reclaim or the dquot shrinker, leading to a situation where tracepoints in the switch statement attempt to access a freed log item.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
