n the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn20_set_output_transfer_func function. Previously, set_output_gamma was being checked for null at line 1030, but then it was being dereferenced without any null check at line 1048. This could potentially lead to a null pointer dereference error if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma at line 1048.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Agregar comprobación NULL para el puntero de función en dcn20_set_output_transfer_func Esta confirmación agrega una comprobación NULL para el puntero de función set_output_gamma en la función dcn20_set_output_transfer_func. Anteriormente, se estaba comprobando que set_output_gamma no fuera nulo en la línea 1030, pero luego se estaba desreferenciando sin ninguna comprobación NULL en la línea 1048. Esto podría conducir potencialmente a un error de desreferencia de puntero nulo si set_output_gamma es nulo. Para solucionar esto, ahora nos aseguramos de que set_output_gamma no sea nulo antes de desreferenciarlo. Hacemos esto agregando una comprobación NULL para set_output_gamma antes de la llamada a set_output_gamma en la línea 1048.
