Vulnerability from fkie_nvd - Published: 2026-03-25 11:16 - Updated: 2026-04-23 21:17

Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: pinctrl: pinconf-generic: Fix memory leak in pinconf_generic_parse_dt_config() In pinconf_generic_parse_dt_config(), if parse_dt_cfg() fails, it returns directly. This bypasses the cleanup logic and results in a memory leak of the cfg buffer. Fix this by jumping to the out label on failure, ensuring kfree(cfg) is called before returning.
