CVE-2024-57834

Kernel crash via uninitialized vidtv mux dereference

Published Feb 27, 2025 · Updated May 11, 2026

NULL pointer dereference in affected Linux kernel releases from 5.10 allows local users to crash the kernel through the vidtv test driver. The vidtv_start_streaming path can leave dvb->mux uninitialized when vidtv_mux_init fails, but vidtv_mux_stop_thread dereferences that null mux pointer during feed teardown. Reaching the flaw requires a local user to exercise the vidtv test driver after mux initialization fails, and exploitation interrupts the host by crashing its kernel.
