  3. CVE-2024-49912
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Handle null 'stream_status' in 'planes_changed_for_existing_stream' This commit adds a null check for 'stream_status' in the function 'planes_changed_for_existing_stream'. Previously, the code assumed 'stream_status' could be null, but did not handle the case where it was actually null. This could lead to a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 planes_changed_for_existing_stream() error: we previously assumed 'stream_status' could be null (see line 3774)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Controlar 'stream_status' nulo en 'planes_changed_for_existing_stream' Esta confirmación agrega una comprobación NULL para 'stream_status' en la función 'planes_changed_for_existing_stream'. Anteriormente, el código asumía que 'stream_status' podía ser nulo, pero no manejaba el caso en el que realmente era nulo. Esto podría llevar a una desreferencia de puntero nulo. Reportado por smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 error planes_changed_for_existing_stream(): anteriormente asumimos que 'stream_status' podía ser nulo (ver línea 3774)
