Availability impact via time module UAF
Published Aug 17, 2026 · Updated Aug 17, 2026
Use-after-free in the time and time zone module in Huawei HarmonyOS 6.1.0 allows attackers to affect availability via unspecified vectors. The published record identifies the locus only as the time and time zone module and discloses that code in that module accesses memory after it has been freed, but it does not name the vulnerable function, trigger, or reachable interface. Because Huawei published only an availability impact, triage depends on whether HarmonyOS 6.1.0 devices expose that module to untrusted local code or other attacker-controlled inputs.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
