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...

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

The Linux kernel allows user-space processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL, which disables the speculation feature, as well as through the use of seccomp. We noticed that on virtual machines of at least one major cloud provider, the kernel still left the victim...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/vmscape: Added conditional IBPB mitigation VMSCAPE is a vulnerability that exploits insufficient branch predictor isolation between a guest and a userspace hypervisor such as QEMU. Existing mitigations already protect the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/hyperv: Disabling IBT when the hypercall page lacks the ENDBR instruction. On hardware that supports Indirect Branch Tracking IBT, Hyper-V VMs with ConfigVersion 9.3 or later support IBT in the guest. However, current version...

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 – Vulnerabilities in Linux 5.10, Linux 5.15

The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ibprctlset function updates the Thread Information Flags TIFs for the task and updates the SPECCTRL MSR in the function speculationctrlupdate, but the IBPB is only issued at the next schedul...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: mac80211: Fixed an underflow in staticbranchdec for aqldisable. syzbot reported an underflow in staticbranchdec in aqlenablewrite. 0 The issue arises because aqlenablewrite does not serialize concurrent write operations ...

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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

There is a vulnerability in the Linux Kernel within the KVM framework: nVMX, which allows for speculative execution attacks. L2 can execute Spectre v2 attacks on L1, as L1 believes it does not need retpolines or IBPB after executing L2, due to KVM L0 advertising eIBRS support to L1. An attacker a...

Astra Linux – Vulnerability in Firefox and Thunderbird

On arm64, an WASM brtable instruction with many entries could cause the label to be too far away from the instruction, leading to truncation and incorrect computation of the branch address. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1,...
