4cde969b4cdb9c88d249a1bc077eb95b786a6396542e2655f3fdef84c6102638Ubuntu Security Notice 1072-1 - Multiple vulnerabilities have been discovered and addressed in the Linux kernel. Gleb Napatov discovered that KVM did not correctly check certain privileged operations. Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. Dan Jacobson discovered that ThinkPad video output was not correctly access controlled. Various other issues have also been addressed.
812b3e28ec2f6132fd1f95415c8a0227bd33b2de0533cab3591015f15aead3cbMandriva 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.
65f216d797172b0ef5fb798cc0c6bfad2e1a9bea20f92874be16068901dbc644Ubuntu Security Notice 1057-1 - Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. A remote attacker could exploit this to read or write disk blocks that had changed file assignment or had become unlinked, leading to a loss of privacy. Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy. Kees Cook and Vasiliy Kulikov discovered that the shm interface did not clear kernel memory correctly. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.

Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. Kees Cook discovered that the Intel i915 graphics driver did not correctly validate memory regions. Various other issues have also been addressed.
