CVE-2022-23824 [MEDIUM] CWE-1037 hw: cpu: AMD: IBPB and Return Address Predictor Interactions
hw: cpu: AMD: IBPB and Return Address Predictor Interactions
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.
A flaw was found in hw. The AMD CPUs can be attacked similar to the previously known Spectre Variant 2 (CVE-2017-5715). This issue affects AMD CPUs where the OS relies on IBPB to flush the return address predictor. As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks.
