  "description": "In the Linux kernel, the following vulnerability has been resolved:  hwmon: (pmbus/adm1266) cap PDIO scan in get_multiple at ADM1266_PDIO_NR  adm1266_gpio_get_multiple() iterates the PDIO portion of the caller-supplied mask using  \tfor_each_set_bit_from(gpio_nr, mask, \t\t\t      ADM1266_GPIO_NR \u002B ADM1266_PDIO_STATUS) { \t\t... \t}  where ADM1266_PDIO_STATUS is the PMBus command code (0xE9, i.e. 233), not the number of PDIO pins.  The intended upper bound is ADM1266_GPIO_NR \u002B ADM1266_PDIO_NR = 25.  gpiolib hands in a mask sized for gc.ngpio (= 25 bits on this chip), so the iteration walks find_next_bit() up to 242, reading up to 217 extra bits (a handful of unsigned-long words: four on 64-bit, seven on 32-bit) of whatever lives past the end of the mask in the caller\u0027s stack.  Any incidental set bit in that range then drives a set_bit(gpio_nr, bits) call that writes past the end of the caller-supplied bits array too -- both out-of-bounds.  Substitute ADM1266_PDIO_NR for the constant so the scan stops at the last real PDIO bit.",
