EUVD-2026-38042

An integer overflow vulnerability was found in the virtio-snd device via PCMINFO requests from the guest. A malicious guest can provide out-of-bounds stream counts, potentially leading to unbounded memory allocation on the host and a denial of service condition...

EUVD-2024-55617

Improper input validation for DIMM serial presence detect SPD metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to potentially overwrite guest memory resulting in loss of guest data integri...

CVE-2024-21944

Improper input validation for DIMM serial presence detect SPD metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to potentially overwrite guest memory resulting in loss of guest data integri...

CVE-2024-21944

CVE-2024-21944 maps to an AMD SEV-SNP/ASP issue where SPD metadata can be improperly validated. Research show BadRAM-style exploits that can cause a memory module to misreport size, enabling a local attacker with ring0 or physical access to overwrite guest memory and compromise guest data integri...

PT-2026-45766

Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the BIOS INT 0x15 / E820 memory map handler, implemented in napoca/guests/bios handlers.c. The handler computes a destination offset into the guest RealModeMemory buffer from guest-controlled ES and EDI...

kernel: mm: thp: deny THP for files on anonymous inodes

A flaw was found in the Linux kernel's Transparent Huge Pages THP mechanism. This vulnerability occurs because the filethpenabled function incorrectly allows THP for files on anonymous inodes, which are not designed for this feature. An attacker could potentially exploit this by manipulating...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: The existing SPTE is preserved even when creating an MMIO SPTE. When installing an emulated MMIO SPTE, do so after preserving the existing SPTE if it is shadow-present. However, the fix proposed in commit 54aa15c6bd...

Linux Distros Unpatched Vulnerability : CVE-2026-43214

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: x86: Add SRCU protection for reading PDPTRs in getsregs2 Add SRCU read-side protection when reading PDPTR registers in getsregs2. Reading PDPTRs may trigge...

EUVD-2026-27602

In the Linux kernel, the following vulnerability has been resolved: mshv: Fix infinite fault loop on permission-denied GPA intercepts Prevent infinite fault loops when guests access memory regions without proper permissions. Currently, mshvhandlegpaintercept attempts to remap pages for all faults...

CVE-2026-43214

The CVE-2026-43214 issue concerns Linux kernel KVM on x86: when reading PDPTRs in __get_sregs2(), SRCU read-side protection was missing. The root cause is that kvm_pdptr_read() may dereference guest memory via a chain (svm_cache_reg -> load_pdptrs -> kvm_vcpu_read_guest_page -> kvm_vcpu_...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: kvm: Avoid speculative attacks from out-of-range memslot accesses. KVM’s mechanism for accessing guest memory converts a guest physical address gpa to a host virtual address using the right-shifted gpa also known as gfn and a...

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

In the Linux kernel, the following vulnerability has been resolved: KVM: x86 – Mark the target gfn of the emulated atomic instruction as dirty When emulating an atomic access on behalf of the guest, mark the target gfn as dirty if the CMPXCHG instruction attempts to be executed and fails without ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: nSVM: fixed a potential NULL dereference during nested migration. It turns out that due to feedback from reviews and/or changes in relocation locations, I accidentally moved the call to nestedsvmloadcr3 too early, befor...
