DESCRIPTION

* CVE-2013-1819: Denial-of-service in XFS filesystems.

Incorrect validation of block numbers could allow local users to cause a
denial-of-service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by leveraging the ability to
mount an XFS filesystem containing a metadata inode with an invalid
extent map.


* System hang in zram swap free under high memory pressure.

Incorrect locking in the zram swap freeing path could result in a system
hang when the system is under high memory pressure.
