GHSA-5599-VJ49-3FH3

Vulnerability from github – Published: 2026-03-25 12:30 – Updated: 2026-04-23 21:31

Details

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.

Severity

5.5 (Medium)
