Description
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."
Ubuntu-Description
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.
