In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Validate GPIO pin LUT table size before iterating

[Why&How]

The GPIO pin table parsers in get_gpio_i2c_info() and

bios_parser_get_gpio_pin_info() derive an element count from the VBIOS

table_header.structuresize field, then iterate over gpio_pin[] entries.

However, GET_IMAGE() only validates that the table header itself fits

within the BIOS image. If the VBIOS reports a structuresize larger than

the actual mapped data, the loop reads past the end of the BIOS image,

causing an out-of-bounds read.

Fix this by calling bios_get_image() to validate that the full claimed

structuresize is accessible within the BIOS image before entering the

loop in both functions.

(cherry picked from commit ba5e95b43b773ae1bf1f66ee6b31eb774e65afe3) (NVD)
