Description
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.
Affected configurations
• linux linux kernel (< 5.9.0)
• linux linux kernel 5.9.0
• canonical ubuntu linux 18.04
• canonical ubuntu linux 20.04
• debian debian linux 9.0
