However, coreboot_table_probe() replaces the platform resource length with header and table sizes supplied by firmware before mapping the full table.</p> <p>A malformed table can overflow the 32-bit size addition or advertise an extent beyond the resource, causing the driver to map and parse memory outside the resource. A resource shorter than the fixed header is also mapped as though it contained a complete header.</p> <p>Reject resources shorter than the fixed header. After validating the signature, require a complete header, calculate the advertised extent with overflow checking, and reject extents beyond the resource before remapping the table.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>firmware: coreboot: Validate table bounds</p> <p>The existing coreboot_table_populate() bounds checks limit individual entries to the mapped length.
