Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
 - SuperH RISC architecture,
 - MMC subsystem,
 - Network drivers,
 - SCSI drivers,
 - GFS2 file system,
 - IPv4 networking,
 - IPv6 networking,
 - HD-audio driver,
