ARM kernels. A local attacker could exploit this flaw to cause a
denial of service or gain root privileges. (CVE-2011-1759)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of
service or escalate privileges. (CVE-2011-2182)

The linux kernel did not properly account for PTE pages when deciding
which task to kill in out of memory conditions. A local, unprivileged
could exploit this flaw to cause a denial of service. (CVE-2011-2498)

A flaw was discovered in the TOMOYO LSM's handling of mount system
calls. An unprivileged user could oops the system causing a denial of
service. (CVE-2011-2518)

A flaw was discovered in the Linux kernel's AppArmor security
interface when invalid information was written to it. An unprivileged
