CVE-2022-39189

A flaw was found in the x86 KVM subsystem in kvmstealtimesetpreempted in arch/x86/kvm/x86.c in the Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVMVCPUPREEMPTED situations. Mitigation Mitigation for this issue is...

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls causing a kernel oops condition that results in a denial of service.
