CVE-2022-23960 | 3 Arm, Debian, Xen | 42 Cortex-a57, Cortex-a57 Firmware, Cortex-a65 and 39 more | 2023-01-19 | 1.9 LOW | 5.6 MEDIUM |
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 obtain sensitive information. | |||||
CVE-2022-25368 | 2 Amperecomputing, Arm | 44 Ampere Altra, Ampere Altra Firmware, Ampere Altra Max and 41 more | 2022-03-15 | 1.9 LOW | 4.7 MEDIUM |
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 can then be used to infer information that should be protected. |
