      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: bound DMA command body size against suffix pointer\n\nvmw_cmd_dma() locates the DMA suffix at\n\n\t(unsigned long) &cmd->body + header->size - sizeof(*suffix)\n\nwithout checking that header->size is large enough to contain both\ncmd->body and the suffix.  An undersized header makes the suffix\npointer underflow back into the previous command in the bounce\nbuffer.  The verifier later writes suffix->maximumOffset, clobbering\nverified fields of an already-relocated earlier command -- a TOCTOU\non the device-visible command stream that lets one command rewrite\nanother's GMR id, surface id, or other authenticated fields.\n\nReject the command if the body is too small for the suffix to fit.",
