3951314e09aedfa23a82d047ac46011aRed Hat Security Advisory 2012-0481-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Numerous reference count leaks were found in the Linux kernel's block layer I/O context handling implementation. This could allow a local, unprivileged user to cause a denial of service. A flaw was found in the Linux kernel's cifs_lookup() implementation. POSIX open during lookup should only be supported for regular files. When non-regular files pipe or other special files) are opened on lookup, it could cause a denial of service.
61e1fccbc6fda27da4682f62f4be5e78Debian Linux Security Advisory 2443-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation.
46acd3222ddefe1b1d906398bff5fbb8Ubuntu Security Notice 1405-1 - Somnath Kotur discovered an error in the Linux kernel's VLAN (virtual lan) and be2net drivers. An attacker on the local network could exploit this flaw to cause a denial of service. Paolo Bonzini discovered a flaw in Linux's handling of the SG_IO ioctl command. A local user, or user in a VM could exploit this flaw to bypass restrictions and gain read/write access to all data on the affected block device. Various other issues were also addressed.
