Q: Which products are affected by CVE-2022-23960?

23 products: xen xen, arm cortex-r7 firmware, arm cortex-r8 firmware, arm cortex-a57 firmware, arm cortex-a65 firmware, and 18 more.

Description

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.
