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
