CVE-2026-53387

Status: AnalyzedHigh (7.1)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Acceso local sin interacción (AV:L/PR:L/UI:N) permite escalada mediante out-of-bounds en kernel. Fallo de array puede causar DoS (A:H) o lectura de memoria (C:H).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
