CVE-2024-47293

Availability loss via inconsistent HAL-WIFI lengths

Published Sep 27, 2024 · Updated Sep 27, 2024

Out-of-bounds write in Huawei HarmonyOS and EMUI allows local users to reduce availability through the HAL-WIFI module. The module incorrectly handles an inconsistent length parameter and writes beyond the intended buffer; Huawei has not disclosed the affected routine or input path. Affected releases are HarmonyOS 3.0.0, 4.0.0, and 4.2.0 and EMUI 13.0.0 and 14.0.0; exploitation requires local access, high privileges, and high-complexity conditions.
