CVE-2022-39189

Published: 2 September 2022

An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations.

From the Ubuntu Security Team

Jann Horn discovered that the KVM subsystem in the Linux kernel did not properly handle TLB flush operations in some situations. A local attacker in a guest VM could use this to cause a denial of service (guest crash) or possibly execute arbitrary code in the guest kernel.
