Ubuntu Security Notice 1187-1 - It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

c71487823755634861f489d8726738a989e9ca187336d6c2634366b8d23bd557Mandriva Linux Security Advisory 2011-029 - Multiple vulnerabilities have been discovered and fixed in the Linux 2.6 kernel. The X.25 implementation does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed data, a different vulnerability than CVE-2010-4164. The bcm_connect function Broadcast Manager in the Controller Area Network implementation in the Linux creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename. The install_special_mapping function in mm/mmap.c does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. Various other issues have also been addressed.
