CVE-2006-1522 Information

Description

The sys_add_key function in the keyring code in Linux kernel 2.6.16.1 and 2.6.17-rc1 and possibly earlier versions allows local users to cause a denial of service (OOPS) via keyctl requests that add a key to a user key instead of a keyring key which causes an invalid dereference in the __keyring_search_one function.
