IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure...
CVE-2022-23824
Summary: CVE-2022-23824 is listed as a Xen-related vulnerability in Debian security advisories and Gentoo GLSA, indicating multiple vulnerabilities in the Xen hypervisor that could lead to privilege escalation, denial of service, or information leaks. The Debian entry explicitly groups CVE-2022-2...
x86: Multiple speculative security issues
ISSUE DESCRIPTION 1 Researchers have discovered that on some AMD CPUs, the implementation of IBPB Indirect Branch Prediction Barrier does not behave according to the specification. Specifically, IBPB fails to properly flush the RAS Return Address Stack, also RSB - Return Stack Buffer - in Intel...
hw: cpu: Intel: Post-barrier Return Stack Buffer Predictions
A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation eIBRS capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer RSB...
hw: cpu: arm64: Spectre-BHB
A new cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, was found in hw. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history stored in the CPU Branch History Buffer, or BHB to influence mispredicted branches within t...
