A flaw was found in the implementation of the Linux kernel's GSS mechanism registration functionality. During this period, memory allocation was not freed when the module was unloaded, leading to a memory leak. This flaw allows an attacker with the ability to repeat loads and unloads, to cause the system to run out of free memory and crash eventually.
