Multiple speculative security issues

ISSUE DESCRIPTION Note: Multiple issues are contained in this XSA due to their interactions. 1 Researchers at VU Amsterdam have discovered Spectre-BHB, pertaining to the use of Branch History between privilege levels. ARM have assigned CVE-2022-23960. Intel have assigned CVE-2022-0001 Branch...

UBUNTU-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...
