Arm

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.

The AES instructions on the ARMv8 platform do not have an algorithm that is "intrinsically resistant" to side-channel attacks.

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB.

In certain circumstances, an issue in Arm Cortex-A57, Cortex-A72 (revisions before r1p0), Cortex-A73 and Cortex-A75 may allow an adversary to gain a weak form of control over the victim's branch history.

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.
