CVE-2026-24927

Service interruption via frequency-module use-after-free

Published Feb 6, 2026 · Updated Feb 6, 2026

Use-after-free in the frequency modulation module of affected Huawei EMUI and HarmonyOS releases allows local users to interrupt service. Huawei maps the flaw to use-after-free but has not disclosed the affected function, the freed object, or the operation that accesses it after release. Local low-privileged access is required, and the documented consequence is limited to availability; the vendor does not specify a crash, hang, or reboot.
