A flaw was found in the kernels implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-free and create a situation where it may be possible to escalate privileges on the system.References:https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9d8e7007dc7c4d7c8366739bbcd3f5e51dcd470f
