Summary: kernel security update

Details: Security Fix(es): 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://www.spinics.net/lists/stable/msg536418.html Upstream commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=57bc3d3ae8c14df3ceb4e17d26ddf9eeab304581(CVE-2022-2964) A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.(CVE-2022-3028)
