Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: dm ioctl: prevents potential Spectre v1 exploits. It seems that cmd could be a Spectre v1 exploit, as it is provided by a user and used as an array index. This vulnerability prevents the contents of kernel memory from being leake...

Astra Linux – Vulnerability in Linux 5.10

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 indicating support for eIBRS to L1. An attacke...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

The Cross-Privilege Spectre v2 vulnerability allows attackers to bypass all deployed mitigations, including the recently introduced FineIBT, and to leak arbitrary Linux kernel memory on Intel systems...

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...
