CVE-2025-58287

Information disclosure via office service use-after-free

Published Oct 11, 2025 · Updated Oct 11, 2025

Use-after-free in the office service in Huawei HarmonyOS 5.0.1 and 5.1.0 allows attackers to disclose service data via local access. Huawei identifies the office service as the affected locus but has not published the freed object, triggering input, or invalid memory operation. Published assessments disagree on whether exploitation requires user interaction or low privileges, while the vendor bounds the reported consequence to loss of service confidentiality.
