Paolo Bonzini discovered a flaw in Linuxβs 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. (CVE-2011-4127)
A flaw was found in KVMβs Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. (CVE-2011-4622)
A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. (CVE-2012-0038)
A flaw was found in the Linux kernelβs ext4 file system when mounting a corrupt filesystem. A user-assisted remote attacker could exploit this flaw to cause a denial of service. (CVE-2012-2100).
