Cortex A78 Firmware
Monthly
Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. Rated medium severity (CVSS 5.6).
Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history (stored in the CPU BHB) to influence mispredicted branches in the victim's hardware context. Rated medium severity (CVSS 4.7).
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Rated medium severity (CVSS 5.6). Public exploit code available and EPSS exploitation probability 94.3%.
