CVE-2022-25368

CVE-2022-23960 describes Spectre-BHB: an attack on ARM Cortex and Neoverse CPUs that abuse the Branch History Buffer (BHB) to influence mispredicted branches, enabling a cache-related side-channel and potential information disclosure across security contexts. Affected: ARM Cortex and Neoverse pro...

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...

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...
