Detail

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: core: Clear table_sz when rproc_shutdown

There is case as below could trigger kernel dump: Use U-Boot to start remote processor(rproc) with resource table published to a fixed address by rproc. After Kernel boots up, stop the rproc, load a new firmware which doesn't have resource table ,and start rproc.

When starting rproc with a firmware not have resource table, `memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will trigger dump, because rproc->cache_table is set to NULL during the last stop operation, but rproc->table_sz is still valid.

This issue is found on i.MX8MP and i.MX9.

Dump as below: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Mem abort info:
