CVE-2026-0665

An off-by-one error was found in QEMU's KVM Xen guest support. A malicious guest could use this flaw to trigger out-of-bounds heap accesses in the QEMU process via the emulated Xen physdev hypercall interface, leading to a denial of service or potential memory corruption...

CVE-2025-14876

CVE-2025-14876 affects the virtio-crypto device in QEMU. The AKCIPHER path has a missing length limit, causing unbounded memory allocation and potential host DoS (QEMU process termination) via a malicious guest. Affected products include qemu/kvm; advisories from SUSE openSUSE and other vendors r...

CVE-2025-14876 Qemu-kvm: unbounded allocation in virtio-crypto

A flaw was found in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, leading to uncontrolled memory allocation. This can result in a denial of service DoS on the host system by causing the QEMU process to terminate...
