In the Linux kernel, the following vulnerability has been resolved:
platform/x86: think-lmi: Free system certificate signatures
Multi-certificate support also allows the system authentication object
to store ->signature and ->save_signature, which leak when the driver is
removed. Free the signatures to avoid leaking memory.
