Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A known cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, reappears in the new hw AmpereOne. 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 mispredict...

Exploiting Inaccurate Branch History in Side-Channel Attacks

Modern out-of-order CPUs heavily rely on speculative execution for performance optimization, with branch prediction serving as a cornerstone to minimize stalls and maximize efficiency. Whenever shared branch prediction resources lack proper isolation and sanitization methods, they may originate...

Linux Distros Unpatched Vulnerability : CVE-2023-3006

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A known cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, becomes actual again for the new hw AmpereOne. Spectre-BHB is...

CVE-2024-2201

A cross-privilege Spectre v2 vulnerability allows attackers to bypass all deployed mitigations, including the recent FineIBT, and to leak arbitrary Linux kernel memory on Intel systems...

kernel: x86/bhi: Avoid warning in #DB handler due to BHI mitigation

A denial of service vulnerability was found in the Linux kernel. When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set, then entrySYSENTERcompat uses CLEARBRANCHHISTORY and calls the clearbhbloop before the TF flag is cleared. This causes the DB handler excdebugkernel to iss...
