CVE-2022-23960

CVE-2022-23960 affects Arm Cortex and Neoverse processors. It is a Spectre-BHB side-channel issue where shared branch history in the Branch History Buffer can influence mispredicted branches, enabling potential information disclosure through cache allocation. Documents note mitigations include de...

CVE-2022-23960

A new cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, was found in hw. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history stored in the CPU Branch History Buffer, or BHB to influence mispredicted branches within t...

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...
