CVE-2011-4110

Published: 23 November 2011

The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allows local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and "updating a negative key into a fully instantiated key."

From the Ubuntu security team

A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system.
