CVE-2022-29901: Intel core i7-6500u firmware information exposure vulnerability

Intel · Core I7 6500u Firmware

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.
