CVE-2006-1522 (CCN-25722)

Assigned:2006-04-10
Published:2006-04-10
Updated:2023-02-13
Summary: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.
