CVE-2022-49615

Kernel panic via pre-probe component dereference

Published Feb 26, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux rt711-sdca codec driver allows local users to trigger a kernel panic during initialization I/O errors. Initial settings execute before probe assigns rt711->component, and the I/O error path dereferences component->dev instead of the initialized slave->dev. The crash requires an affected kernel with the rt711-sdca driver and compatible codec hardware to encounter an initialization I/O error; no confidentiality or integrity impact is reported.
