CVE-2026-64097

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Validate GPIO pin LUT table size before iterating<br /> <br /> [Why&amp;How]<br /> The GPIO pin table parsers in get_gpio_i2c_info() and<br /> bios_parser_get_gpio_pin_info() derive an element count from the VBIOS<br /> table_header.structuresize field, then iterate over gpio_pin[] entries.<br /> However, GET_IMAGE() only validates that the table header itself fits<br /> within the BIOS image. If the VBIOS reports a structuresize larger than<br /> the actual mapped data, the loop reads past the end of the BIOS image,<br /> causing an out-of-bounds read.<br /> <br /> Fix this by calling bios_get_image() to validate that the full claimed<br /> structuresize is accessible within the BIOS image before entering the<br /> loop in both functions.<br /> <br /> (cherry picked from commit ba5e95b43b773ae1bf1f66ee6b31eb774e65afe3)
