CVE-2018-13095
A denial of service (memory corruption and BUG) can occur for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork.
Does this matter?
Lower severity and a low EPSS score (1.53%). Track it; it rarely justifies an emergency change on its own.
