** Description changed: - There is a NULL pointer deref in the user-defined key type whereby - updating a negative key into a fully instantiated key will cause an oops - to occur when the code attempts to free the non-existent old payload. + 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." Break-Fix: - 9f35a33b8d06263a165efe3541d9aa0cdbd70b3b
