Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel before version 6.9, a trusted-to-non-trusted hypervisor can inject Virtual Interrupt 29 VC at any point in time and can trigger its handler. This affects AMD SEV-SNP and AMD SEV-ES...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: x86/kvm: The teardown of PV features also occurs during boot-up. Various PV features Async PF, PV EOI, steal time work through memory shared with the hypervisor. When we resume from hibernation, we must properly teardown all...

Astra Linux – Vulnerability in Xen

Inappropriate x86 IOMMU timeout detection/handling: IOMMU processes commands that are issued in parallel with the operation of the CPUs that issue those commands. In the current implementation in Xen, asynchronous notifications of the completion of such commands are not used. Instead, the issuing...

Astra Linux – Vulnerability in amd64-microcode

Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to influence the cache line write-back behavior of the CPU, resulting in a potential loss of integrity of the guest virtual machine VM memory...

Xen: Stale TLB Entry Ahead of Page Scrubbing (XSA-511)

x86 PV guests can free memory pages while still keeping a stale TLB entry pointing to them. A TLB flush is only issued by Xen if needed when the page is re-used. Since it's possible for the page to be scrubbed ahead of the TLB flush, there's a window where a PV guest can modify an already scrubbe...
