Ubuntu Security Notice 4118-1 - It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice 3879-1 - Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an out of bounds write when updating the journal for an inline file. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service. Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem of the Linux kernel did not properly initialize new files in some situations. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
