Summary
In the Linux kernel, the following vulnerability has been resolved: iio: light: veml6075: add bounds check to veml6075_it_ms index veml6075_it_ms has 5 elements but VEML6075_CONF_IT can yield values 0-7. If it returns a value >= 5, this causes an out-of-bounds array access.
Add a bounds check and return -EINVAL if the index is out of range. The problem values are reserved so should never be read from the register.
Hence this is hardening against fault device, missprogramming or bus corruption. The driver performs an out-of-bounds array access when processing certain index values from the `VEML6075_CONF_IT` register.
This issue could potentially lead to system instability or a denial of service if triggered by a faulty device, misprogramming, or bus corruption. Red Hat severity: Moderate.
Weakness: CWE-787. Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
