CVE-2026-46286
leds: qcom-lpg: Check for array overflow when selecting the high resolution
Description
In the Linux kernel, the following vulnerability has been resolved: leds: qcom-lpg: Check for array overflow when selecting the high resolution When selecting the high resolution values from the array, FIELD_GET() is used to pull from a 3 bit register, yet the array being indexed has only 5 values in it. Odds are the hardware is sane, but just to be safe, properly check before just overflowing and reading random data and then setting up chip values based on that.

Action Type Old Value New Value Added Translation Title: Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: leds: qcom-lpg: Comprobar el desbordamiento de la matriz al seleccionar la alta resolución Al seleccionar los valores de alta resolución de la matriz, se utiliza FIELD_GET() para extraer de un registro de 3 bits, sin embargo, la matriz que se está indexando tiene solo 5 valores. Lo más probable es que el hardware sea correcto, pero solo para estar seguros, comprobar correctamente antes de simplemente desbordarse y leer datos aleatorios y luego configurar los valores del chip basándose en eso. -
