| Subject: CVE-2025-40114: iio: light: Add check for array bounds in veml6075_read_int_time_ms |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2025-40114 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
