Descriptions

In the Linux kernel, the following vulnerability has been resolved: iio: light: Add check for array bounds in veml6075_read_int_time_ms The array contains only 5 elements, but the index calculated by
veml6075_read_int_time_index can range from 0 to 7,
which could lead to out-of-bounds access. The check prevents this issue. Coverity Issue
CID 1574309: (#1 of 1): Out-of-bounds read (OVERRUN)
overrun-local: Overrunning array veml6075_it_ms of 5 4-byte
elements at element index 7 (byte offset 31) using
index int_index (which evaluates to 7) This is hardening against potentially broken hardware. Good to have
but not necessary to backport.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iio: light: Agregar comprobación de los límites de matriz en veml6075_read_int_time_ms La matriz contiene solo 5 elementos, pero el índice calculado por veml6075_read_int_time_index puede variar de 0 a 7, lo que podría provocar un acceso fuera de los límites. La comprobación evita este problema. Coverity Issue CID 1574309: (#1 de 1): Lectura fuera de los límites (OVERRUN) overrun-local: Desbordamiento de la matriz veml6075_it_ms de 5 elementos de 4 bytes en el índice de elemento 7 (desplazamiento de byte 31) utilizando el índice int_index (que evalúa a 7) Esto es endurecimiento contra hardware potencialmente dañado. Es bueno tenerlo, pero no es necesario retroportarlo.
