CVE-2024-42248

System crash via NULL device-tree node dereference

Published Aug 7, 2024 · Updated May 11, 2026

A NULL pointer dereference in Linux's MA35D1 serial driver allows attackers to crash the system during platform-device probing. ma35d1serial_probe continues after a missing device-tree serial node and passes the NULL of_node value to the clock lookup path. Reachability requires an MA35D1 platform device whose serial node is absent; public sources disclose no network path or ordinary user-controlled input.
