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_...

SUSE-SU-2026:21354-1 Security update for qemu
This update for qemu fixes the following issues: Update to version 10.0.9. Security issues fixed: - CVE-2026-3196: unbounded memory allocation and host denial-of-service via PCMINFO requests sent from the guest bsc1259079. - CVE-2026-3195: heap out-of-bounds write when reading input audio in the...
SUSE CVE-2026-35195
Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of transcoding strings between components contains a bug where the return value of a guest component's realloc is not validated before the host attempts to write through the pointer. This...
AMD: CVE-2023-20585 IOMMU Write Buffer Vulnerability
The vulnerability assigned to this CVE could lead to corruption of guest encrypted memory. The mitigation for this vulnerability requires a Windows update. This CVE is being documented in the Security Update Guide to announce that the latest builds of Windows enable the mitigation and provide...

CVE-2026-23401
CVE-2026-23401: In the Linux kernel KVM x86/mmu, a race allowed installing an MMIO SPTE without first zapping an existing shadow-present SPTE when guest memory writes occurred outside KVM’s scope. This could enable a guest‑memory–related fault to leave a shadow SPTE intact when an MMIO SPTE is in...
Contrast BadAML injection allows arbitrary code execution
BadAML BadAML is an AML injection attack that exploits the ACPI interface and allows arbitrary code execution in a confidential VM. The attack was first published in 2024: - - Impact An attacker with control over the host which is assumed in the attacker model of Contrast can execute malicious AM...
CVE-2026-23375
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...
