Description

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.
