CVE-2024-39434

Local denial of service via unchecked DRM read

Published Sep 27, 2024 · Updated Sep 27, 2024

An out-of-bounds read in the DRM service on Unisoc chipsets running Android 13 or Android 14 allows local users to cause denial of service. The service reads beyond an intended buffer because it omits a bounds check; the vendor has not disclosed the input, function, or code path. Triggering the flaw requires local access and System execution privileges, and the published consequence is limited to service interruption.
