  "summary": "firmware: coreboot: Validate table bounds",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: coreboot: Validate table bounds\n\nThe existing coreboot_table_populate() bounds checks limit individual\nentries to the mapped length.  However, coreboot_table_probe() replaces\nthe platform resource length with header and table sizes supplied by\nfirmware before mapping the full table.\n\nA malformed table can overflow the 32-bit size addition or advertise an\nextent beyond the resource, causing the driver to map and parse memory\noutside the resource.  A resource shorter than the fixed header is also\nmapped as though it contained a complete header.\n\nReject resources shorter than the fixed header.  After validating the\nsignature, require a complete header, calculate the advertised extent\nwith overflow checking, and reject extents beyond the resource before\nremapping the table.",
