CVE-2022-0516: A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for s390 in the Linux kernel.

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.92-2; linux (Debian:12) 5.16.10-1.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.92-2; linux (Debian:12) 5.16.10-1 or later.
