A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file
system metadata validator in XFS can cause an inode with a valid,
user-creatable extended attribute to be flagged as corrupt. This can lead
to the filesystem being shutdown, or otherwise rendered inaccessible until
it is remounted, leading to a denial of service. The highest threat from
this vulnerability is to system availability.
