CVE-2022-29901

MEDIUM5.6

Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)

Published Jul 12, 2022

Modified 1 years ago

No fix available

Details

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.
