n the Linux kernel, the following vulnerability has been resolved: ptp: ocp: Fix NULL dereference in Adva board SMA sysfs operations On Adva boards, SMA sysfs store/get operations can call __handle_signal_outputs() or __handle_signal_inputs() while the `irig` and `dcf` pointers are uninitialized, leading to a NULL pointer dereference in __handle_signal() and causing a kernel crash. Adva boards don't use `irig` or `dcf` functionality, so add Adva-specific callbacks `ptp_ocp_sma_adva_set_outputs()` and `ptp_ocp_sma_adva_set_inputs()` that avoid invoking `irig` or `dcf` input/output routines.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ptp: ocp: Corregir la desreferencia NULL en las operaciones sysfs de SMA de la placa Adva En las placas Adva, las operaciones de almacenamiento/obtención de SMA sysfs pueden llamar a __handle_signal_outputs() o __handle_signal_inputs() mientras los punteros `irig` y `dcf` no están inicializados, lo que provoca una desreferencia de puntero NULL en __handle_signal() y causa un fallo del kernel. Las placas Adva no usan la funcionalidad `irig` o `dcf`, así que añada las devoluciones de llamada específicas de Adva `ptp_ocp_sma_adva_set_outputs()` y `ptp_ocp_sma_adva_set_inputs()` que evitan invocar las rutinas de entrada/salida `irig` o `dcf`.
