In the Linux kernel, the following vulnerability has been resolved:

iio: accel: kionix-kx022a: Fix array boundary check

The driver performs a sanity check for an array size, when converting a register value to an array index. The check incorrectly accepts the sizeof(array) as a last index, when last valid index should be sizeof(array) - 1.

Fix the check by bailing out when index >= sizeof(array).

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.17 %
Percentile among all scored CVEs: 6
Score date: 10/20/2026

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).
