CVE-2005-2099

Linux Kernel < 2.6.12.5 - Denial of Service via Keyring Destructor Null Dereference

Title source: llm
STIX 2.1

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.
