CVE-2024-37185

Code execution via ArkCompiler out-of-bounds write

Published Jul 2, 2024 · Updated Aug 2, 2024

Out-of-bounds write in OpenHarmony 4.0.0 through 4.0.1 allows remote authenticated users to execute code in pre-installed apps. The flaw resides in the ArkCompiler eTS Runtime, but OpenHarmony has not disclosed the affected operation or how input crosses the write boundary. Exploitation requires adjacent-network access and low privileges, and successful memory corruption executes code in a pre-installed app context.
