CVE-2010-1437

Race condition in the find_keyring_by_name function in
security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows
local users to cause a denial of service (memory corruption and system
crash) or possibly have unspecified other impact via keyctl session
commands that trigger access to a dead keyring that is undergoing deletion
by the key_cleanup function.
