CVE-2025-40114 | iio: light: Add check for array bounds in veml6075_read_int_time_ms

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.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
