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.

Affected products

Linux kernel: 2.6.0, 2.6.0-test1, 2.6.0-test10, 2.6.0-test11, 2.6.0-test2, 2.6.0-test3 (+42)
