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...

CVE-2022-23960

CVE-2022-23960 affects Arm Cortex and Neoverse processors. It is a Spectre-BHB side-channel issue where shared branch history in the Branch History Buffer can influence mispredicted branches, enabling potential information disclosure through cache allocation. Documents note mitigations include de...

CVE-2021-41848

An issue was discovered in Luna Simo PPR1.180610.011/202001031830. It mishandles software updates such that local third-party apps can provide a spoofed software update file that contains an arbitrary shell script and arbitrary ARM binary, where both will be executed as the root user with an...

Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

USN-5318-1: Linux kernel vulnerabilities | Cloud Foundry

New Exploit Bypasses Existing Spectre-V2 Mitigations in Intel, AMD, Arm CPUs

Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm, and stage speculative execution attacks such as Spectre to leak sensitive information from host memory. Attacks like Spectre are designed to bre...
