CVE-2024-43852

In the Linux kernel, the following vulnerability has been resolved: hwmon: (ltc2991) re-order conditions to fix off by one bug LTC2991_T_INT_CH_NR is 4. The st->temp_en[] array has LTC2991_MAX_CHANNEL (4) elements. Thus if "channel" is equal to LTC2991_T_INT_CH_NR then we have read one element beyond the end of the array. Flip the conditions around so that we check if "channel" is valid before using it as an array index.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: hwmon: (ltc2991) condiciones de reordenamiento para corregir un error LTC2991_T_INT_CH_NR es 4. La matriz st->temp_en[] tiene elementos LTC2991_MAX_CHANNEL (4). Por lo tanto, si "canal" es igual a LTC2991_T_INT_CH_NR entonces hemos leído un elemento más allá del final de la matriz. Cambie las condiciones para verificar si "canal" es válido antes de usarlo como índice de matriz.
