UnknownEPSS 3.28%

Last modified

CVE-2005-2099 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.28% chance of exploitation in the next 30 days.
