  3. CVE-2024-49913
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for top_pipe_to_program in commit_planes_for_stream This commit addresses a null pointer dereference issue in the `commit_planes_for_stream` function at line 4140. The issue could occur when `top_pipe_to_program` is null. The fix adds a check to ensure `top_pipe_to_program` is not null before accessing its stream_res. This prevents a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed 'top_pipe_to_program' could be null (see line 3906)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Agregar comprobación NULL para top_pipe_to_program en commit_planes_for_stream Esta confirmación soluciona un problema de desreferencia de puntero nulo en la función `commit_planes_for_stream` en la línea 4140. El problema podría ocurrir cuando `top_pipe_to_program` es nulo. La corrección agrega una comprobación para garantizar que `top_pipe_to_program` no sea nulo antes de acceder a su stream_res. Esto evita una desreferencia de puntero nulo. Reportado por smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 Error de commit_planes_for_stream(): anteriormente asumimos que 'top_pipe_to_program' podría ser nulo (consulte la línea 3906)
