Ubuntu Security Notice 864-1 - Kernel packages have been updated. It was discovered that the AX.25 network subsystem did not correctly check integer signedness in certain setsockopt calls. Jan Beulich discovered that the kernel could leak register contents to 32-bit processes that were switched to 64-bit mode. Dave Jones discovered that the gdth SCSI driver did not correctly validate array indexes in certain ioctl calls. Eric Dumazet and Jiri Pirko discovered that the TC and CLS subsystems would leak kernel memory via uninitialized structure members. Earl Chew discovered race conditions in pipe handling. There are about a dozen other issues also addressed.
