remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry()
table->offset[i] is a u32 from firmware, but was stored into a signed
int. A crafted offset like 0xFFFFFFF0 becomes -16, placing hdr 16 bytes
before the table buffer. The subsequent avail check was bypassed
because the negative int was promoted to a large size_t in the
expression "table_sz - offset - sizeof(*hdr)", yielding a large positive
avail and letting the out-of-bounds hdr->type read proceed undetected.
Store the offset as u32 and validate it with unsigned comparisons before
any pointer arithmetic.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
