CVE-2024-38548

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is assigned to mhdp_state->current_mode, and there is a dereference of it in drm_mode_set_name(), which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Fix this bug add a check of mhdp_state->current_mode.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: bridge: cdns-mhdp8546: corrige posible desreferencia del puntero nulo En cdns_mhdp_atomic_enable(), el valor de retorno de drm_mode_duplicate() se asigna a mhdp_state->current_mode, y hay una desreferencia de él en drm_mode_set_name(), lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate(). Solucione este error y agregue una verificación de mhdp_state->current_mode.
