FKIE_CVE-2025-38286

Vulnerability from fkie_nvd - Published: 2025-07-10 08:15 - Updated: 2026-06-17 09:16
Severity
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: pinctrl: at91: Fix possible out-of-boundary access at91_gpio_probe() doesn't check that given OF alias is not available or something went wrong when trying to get it. This might have consequences when accessing gpio_chips array with that value as an index. Note, that BUG() can be compiled out and hence won't actually perform the required checks.
