CVE-2024-23808

Local code execution via frontend out-of-bounds read

Published May 7, 2024 · Updated Aug 1, 2024

Out-of-bounds read in OpenHarmony's Ark compiler frontend before 4.0.1 allows local users to execute code in pre-installed apps. The vendor identifies arkcompiler_ets_frontend but does not disclose the faulty function or input operation; the CNA also reports use-after-free and NULL-dereference paths. Low-privilege local access is required, with reported consequences limited to code execution in a pre-installed app or a crash.
