CVE-2026-23337 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's pin control subsystem, specifically within the pinconf_generic_parse_dt_config() function. This issue arises when the function parse_dt_cfg() fails, causing an early return that bypasses necessary cleanup operations. As a result, the configuration buffer (cfg) is not properly freed, leading to a memory leak. The vulnerability affects the stable versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel official website.
