CVE-2024-43860

Kernel crash via empty remoteproc phandle dereference

Published Aug 17, 2024 · Updated May 11, 2026

A NULL-pointer dereference in affected Linux kernel releases allows local users to crash the kernel through a malformed i.MX remoteproc device tree. In imx_rproc_addr_init(), the phandle counter includes empty entries, while the parsing loop dereferences the NULL value returned by of_parse_phandle(). Reachability requires local low-privileged access and an i.MX remoteproc configuration containing an empty memory-region phandle; the reported consequence is a kernel crash.
