  3. CVE-2022-49616
In the Linux kernel, the following vulnerability has been resolved: ASoC: rt7*-sdw: harden jack_detect_handler Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection. The rt700, rt711 and rt711-sdca are however missing a check on the card pointer, which can lead to NULL dereferences encountered in driver bind/unbind tests.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: rt7*-sdw: endurecer el controlador jack_detect_handler Los controladores de códec de auriculares Realtek normalmente comprueban si la tarjeta está instanciada antes de continuar con la detección del conector. Sin embargo, a los modelos rt700, rt711 y rt711-sdca les falta una comprobación en el puntero de la tarjeta, lo que puede provocar desreferencias NULL en las pruebas de vinculación/desvinculación del controlador.
