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.

Affected configurations

• xen xen • arm cortex-r7 firmware • arm cortex-r8 firmware • arm cortex-a57 firmware • arm cortex-a65 firmware • arm cortex-a65ae firmware • arm cortex-a710 firmware • arm cortex-a72 firmware • arm cortex-a73 firmware • arm cortex-a75 firmware • arm cortex-a76 firmware • arm cortex-a76ae firmware • arm cortex-a77 firmware • arm cortex-a78 firmware • arm cortex-a78ae firmware • arm cortex-x1 firmware • arm cortex-x2 firmware • arm neoverse-e1 firmware • arm neoverse-v1 firmware • arm neoverse n1 firmware • arm neoverse n2 firmware • debian debian linux 9.0 • debian debian linux 10.0
