In the Linux kernel, the following vulnerability has been resolved: remoteproc: imxrproc: Skip over memory region when node value is NULL In imxrprocaddrinit() "nph = ofcountphandlewithargs()" just counts number of phandles. But phandles may be empty. So ofparsephandle() in the parsing loop (0 < a < nph) may return NULL which is later dereferenced. Adjust this issue by adding NULL-return check.
