n the Linux kernel, the following vulnerability has been resolved: nvmem: core: fix cleanup after dev_set_name() If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not put this. While a minimal fix for this would be to add the gpiod_put() call, we can do better if we split device_register(), and use the tested nvmem_release() cleanup code by initialising the device early, and putting the device. This results in a slightly larger fix, but results in clear code. Note: this patch depends on "nvmem: core: initialise nvmem->id early" and "nvmem: core: remove nvmem_config wp_gpio". [Srini: Fixed subject line and error code handing with wp_gpio while applying.]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvmem: core: fix cleanup after dev_set_name(). Si dev_set_name() falla, se filtra nvmem->wp_gpio, ya que la limpieza no lo incluye. Si bien una solución mínima sería añadir la llamada gpiod_put(), podemos mejorar si dividimos device_register() y usamos el código de limpieza nvmem_release() probado, inicializando el dispositivo antes y colocándolo. Esto resulta en una corrección ligeramente mayor, pero con código limpio. Nota: Este parche depende de "nvmem: core: initialise nvmem->id early" y "nvmem: core: remove nvmem_config wp_gpio". [Srini: Se corrigió la línea de asunto y la gestión del código de error con wp_gpio durante la aplicación].
