CVSS 5.800000190734863 MEDIUM
A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation (TLBI) operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local attacker to gain kernel privileges or a guest VM to escape to the hypervisor, resulting in complete system compromise.
