  2. Vulnerabilities (CVE)
  3. CVE-2026-23337
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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: pinctrl: pinconf-generic: Corrección de fuga de memoria en pinconf_generic_parse_dt_config() En pinconf_generic_parse_dt_config(), si parse_dt_cfg() falla, retorna directamente. Esto omite la lógica de limpieza y resulta en una fuga de memoria del búfer cfg. Esto se corrige saltando a la etiqueta out en caso de fallo, asegurando que kfree(cfg) se llame antes de retornar.
