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 unexpectedly.

CVE-2026-0665 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
It was discovered that the UHCI controller implementation of QEMU could be
brought into an invalid state. An attacker inside the guest could possibly
use this issue to cause QEMU to crash, resulting in a denial of service.
(CVE-2024-8354)
It was discovered that QEMU incorrectly handled memory during certain VNC
operations. An remote attacker could possibly use this issue to cause QEMU
to crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2025-11234)
It was discovered that the e1000 network device implementation of QEMU
could be made to write out of bounds. An attacker inside the guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service, or p
