CVE-2025-36934 is a local privilege-escalation vulnerability in the Google Pixel BigWave kernel driver exposed via the BigWave device interface. The flaw is located in the bigo_worker_thread function in private/google-modules/video/gchips/bigo.c and arises from a race condition that can cause a use-after-free condition. Available reporting also associates the issue with concurrent access weaknesses consistent with a race in object lifetime management. Successful exploitation allows an attacker to corrupt kernel memory state from a locally reachable driver interface and obtain kernel-level primitives.
