Folks,

here is a Linux kernel fix
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2c212e1baedcd782b2535a3f86bc491977677c0e
 for an insufficient check in the KVM module for s390.
This was reported last week to linux-distros at openwall. No exploit is available.

According to Red Hat this is now tracked via CVE-2022-0516.
