CVE-2022-50725

Memory-safety fault via double release during initialization

Published Dec 24, 2025 · Updated Dec 24, 2025

Use-after-free in vidtv bridge initialization in the Linux kernel allows attackers to trigger stale memory access during device probing. The error paths in vidtv_bridge_dvb_init call release functions after failed demultiplexer initialization has already cleaned up the same objects. Reachability requires an initialization failure in the vidtv test-driver stack; the public record demonstrates a KASAN-detected fault but not code execution.
