CVE-2022-2153 (GCVE-0-2022-2153)

Vulnerability from cvelistv5 – Published: 2022-08-31 00:00 – Updated: 2024-08-03 00:32
VLAI
Summary
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.
