  3. CVE-2024-49914
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe This commit addresses a null pointer dereference issue in the `dcn20_program_pipe` function. The issue could occur when `pipe_ctx->plane_state` is null. The fix adds a check to ensure `pipe_ctx->plane_state` is not null before accessing. This prevents a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx->plane_state' could be null (see line 1877)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Agregar comprobación NULL para pipe_ctx->plane_state en dcn20_program_pipe Esta confirmación soluciona un problema de desreferencia de puntero nulo en la función `dcn20_program_pipe`. El problema podría ocurrir cuando `pipe_ctx->plane_state` es nulo. La corrección agrega una comprobación para garantizar que `pipe_ctx->plane_state` no sea nulo antes de acceder. Esto evita una desreferencia de puntero nulo. Reportado por smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 Error de dcn20_program_pipe(): anteriormente asumimos que 'pipe_ctx->plane_state' podría ser nulo (consulte la línea 1877)
