  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Validate GPIO pin LUT table size before iterating\n\n[Why\u0026How]\nThe GPIO pin table parsers in get_gpio_i2c_info() and\nbios_parser_get_gpio_pin_info() derive an element count from the VBIOS\ntable_header.structuresize field, then iterate over gpio_pin[] entries.\nHowever, GET_IMAGE() only validates that the table header itself fits\nwithin the BIOS image. If the VBIOS reports a structuresize larger than\nthe actual mapped data, the loop reads past the end of the BIOS image,\ncausing an out-of-bounds read.\n\nFix this by calling bios_get_image() to validate that the full claimed\nstructuresize is accessible within the BIOS image before entering the\nloop in both functions.\n\n(cherry picked from commit ba5e95b43b773ae1bf1f66ee6b31eb774e65afe3)",
