CVE-2024-36501

Privileged memory corruption via boottime out-of-bounds write

Published Jun 14, 2024 · Updated Aug 2, 2024

Out-of-bounds write in the boottime module of Huawei HarmonyOS and EMUI allows local users to alter memory during system startup. Huawei identifies CWE-787 but has not published the affected function, untrusted input, or memory operation that crosses the buffer boundary. Exploitation requires high local privileges and no user interaction; Huawei reports confidentiality, integrity, and availability impact but does not identify the failure mode.
