  3. CVE-2024-49909
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn32_set_output_transfer_func function. Previously, set_output_gamma was being checked for null, but then it was being dereferenced without any null check. This could lead to a null pointer dereference 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.

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 dcn32_set_output_transfer_func Esta confirmación agrega una comprobación NULL para el puntero de función set_output_gamma en la función dcn32_set_output_transfer_func. Anteriormente, se estaba comprobando que set_output_gamma no fuera nulo, pero luego se estaba desreferenciando sin ninguna comprobación NULL. Esto podría provocar una 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. Para ello, agregamos una comprobación NULL para set_output_gamma antes de la llamada a set_output_gamma.
