The AES instructions on the ARMv8 platform do not have an algorithm that is "intrinsically resistant" to side-channel attacks. NOTE: the vendor reportedly offers the position "while power side channel attacks ... are possible, they are not directly caused by or related to the Arm architecture." • https://eprint.iacr.org/2022/230 https://eshard.com/posts/sca-attacks-on-armv8 • CWE-203: Observable Discrepancy •

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. Spectre BHB es una variante de Spectre-v2 en la que el código malicioso usa el historial de bifurcaciones compartido (almacenado en el BHB de la CPU) para influir en las bifurcaciones mal predichas en el contexto de hardware de la víctima. Una especulación causada por estas ramas mal predichas puede entonces ser usada potencialmente para causar la asignación de la caché, la cual puede ser usada para inferir información que debe ser protegida • https://amperecomputing.com/products/security-bulletins/impact-of-spectre-bhb-on-ampere.html https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-23960 https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/spectre-bhb •
CVSS: 5.6EPSS: 0%CPEs: 63EXPL: 0CVE-2022-23960 – hw: cpu: arm64: Spectre-BHB
https://notcve.org/view.php?id=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 obtain sensitive information. Algunos procesadores Arm Cortex y Neoverse versiones hasta 08-03-2022 no restringen apropiadamente la especulación de la caché, también conocida como Spectre-BHB. Un atacante puede aprovechar el historial de bifurcaciones compartido en el Buffer del Historial de Bifurcaciones (BHB) para influir en las bifurcaciones predichas inapropiadamente. • http://www.openwall.com/lists/oss-security/2022/03/18/2 https://developer.arm.com/support/arm-security-updates https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-23960 https://bugzilla.redhat.com/show_bug.cgi?id=2062284 •
