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...
