Feature disruption via M3U8 out-of-bounds read

Published Dec 12, 2024 · Updated Dec 12, 2024

Out-of-bounds read in the M3U8 module in Huawei HarmonyOS 5.0.0 allows remote attackers to disrupt feature operation via M3U8 data. The M3U8 module reads beyond a valid memory boundary while handling M3U8 data, but Huawei has not disclosed the affected routine or failed check. Exploitation requires user interaction and can cause affected features to operate abnormally, with no published confidentiality or integrity impact.
