CVE-2026-23337
Description
A flaw was found in the Linux kernel's pinctrl subsystem, specifically within the pinconf-generic module. This vulnerability occurs when the pinconf_generic_parse_dt_config() function fails to properly deallocate memory, bypassing the intended cleanup logic. This oversight results in a memory leak, which can lead to a gradual degradation of system performance and stability over time.
