CVE-2005-2099 Information

Description

The Linux kernel before 2.6.12.5 does not properly destroy a keyring that is not instantiated properly which allows local users or remote attackers to cause a denial of service (kernel oops) via a keyring with a payload that is not empty which causes the creation to fail leading to a null dereference in the keyring destructor.
