The issue\ncould occur when `head_pipe` is null.\n\nThe fix adds a check to ensure `head_pipe` is not null before asserting\nit. If `head_pipe` is null, the function returns NULL to prevent a\npotential null pointer dereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn32/dcn32_resource.c:2690 dcn32_acquire_idle_pipe_for_head_pipe_in_layer() error: we previously assumed 'head_pipe' could be null (see line 2681)"

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Agregar comprobaci\u00f3n NULL para head_pipe en dcn32_acquire_idle_pipe_for_head_pipe_in_layer Esta confirmaci\u00f3n soluciona un posible problema de desreferencia de puntero nulo en la funci\u00f3n `dcn32_acquire_idle_pipe_for_head_pipe_in_layer`. El problema podr\u00eda ocurrir cuando `head_pipe` es nulo. La correcci\u00f3n agrega una comprobaci\u00f3n para garantizar que `head_pipe` no sea nulo antes de afirmarlo. Si `head_pipe` es nulo, la funci\u00f3n devuelve NULL para evitar una posible desreferencia de puntero nulo.
