| [[MVD_Services|MVD]]: Stack buffer overflow with [[MVDSTD:SetupOutputBuffers]].
 +
| The input total_entries is not validated when initially processing the input entry-list. This fixed-size input entry-list is copied to stack from the command request. The loop for processing this initializes a global table, the converted linearmem->physaddrs used there are also copied to stack(0x8-bytes of physaddrs per entry).
 +
 +
If total_entries is too large, MVD-sysmodule will crash due to reading unmapped memory following the stack(0x10000000). Afterwards if the out-of-bounds total_entries is smaller than that, it will crash due accessing address 0x0, hence this useless.
