CVE-2022-23960

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. Then, cache allocation can allow the attacker to obtai...

Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

CVE-2022-25368

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. Speculation caused by these mispredicted branches can then potentially be used to cause cache allocation, which...
