Remote code execution via out-of-bounds writes
Published Jul 14, 2021 · Updated Aug 3, 2024
Out-of-bounds writes in Google Widevine DRM on Android SoC allow remote attackers to execute arbitrary code via unspecified vectors. Affected functions inadequately validate input before memory writes, permitting writes beyond intended buffer boundaries; Google has not disclosed the exact functions. Exploitation requires user interaction but no additional execution privileges, and successful exploitation grants code execution.
