CVE-2026-95397 · Severity: info · Published 2026-11-10

Android devices use a video decoder to process HEVC-encoded video streams. A buffer overflow in the HEVC decoder's sub_layer_hrd_parameters function could allow an attacker with local access to escalate privileges and gain execution rights on the device. User interaction is required for exploitation.
