Vulnerability from osv_openeuler – Published: 2026-04-17 11:10 – Updated: 2026-08-06 11:10 – Source website

Summary

qemu security update

Details

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

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-2025-14876)

Severity

5.5 (Medium)
