Ubuntu Security Notice 1093-1 - Joel Becker discovered that OCFS2 did not correctly validate on-disk symlink structures. Ben Hutchings discovered that the ethtool interface did not correctly check certain sizes. Eric Dumazet discovered that many network functions could leak kernel stack contents. Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. A large number of additional vulnerabilities have also been address.

Mandriva 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.
