Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
How to mitigate CVE-2005-2099
Install update from vendor's repository.
