CVE-2025-14876 is a vulnerability in the virtio-crypto device of QEMU version 7.1.0 where a missing length limit in the AKCIPHER path allows a malicious guest OS to trigger uncontrolled memory allocation. This flaw can cause the QEMU process on the host to terminate unexpectedly, resulting in a denial of service (DoS). The vulnerability has a CVSS score of 5.5, indicating medium severity. No known exploits are reported in the wild. There is no explicit vendor advisory content confirming a patch or mitigation status.
