Astra Linux – Vulnerability in Linux 5.10, Linux

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...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/bhi: Avoid warnings in the DB handler due to BHI mitigation When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set, then entrySYSENTERcompat uses CLEARBRANCHHISTORY and calls clearbhbloop before the TF fl...

Astra Linux – Vulnerability in Linux, Linux 5.10

Certain Arm Cortex and Neoverse processors, as of 2022-03-08, do not properly prevent cache speculation, also known as Spectre-BHB. Attackers can exploit the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. As a result, cache allocation may allow attacker...

CVE-2026-43261

The CVE-2026-43261 entry concerns the Linux kernel ARM64 arm64: TSV110 Spectre-BHB mitigation. The root cause is Spectre-BHB leakage via branch-prediction side channels on TSV110; mitigation consists of adding the TSV110 MIDR to the software mitigation list in the kernel. Affected component: Linu...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: arm64: bpf: Added BHB mitigation to the epilogue for cBPF programs. A malicious BPF program may manipulate the branch history to influence what the hardware speculates will happen next. Upon exiting a cBPF program, the BHB...

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...
