DEBIAN-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...

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

Severity High Vendor Canonical Ubuntu Versions Affected Canonical Ubuntu 18.04 Description Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2022-256...

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...

CVE-2022-25368

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...

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...
