[PATCH 0/2] media: videobuf2: make sure bytesused is smaller than the buffer size

Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx> · Mon, 8 Nov 2021 21:39:31 +0200

Add a WARN_ON in vb2_set_plane_payload if bytesused is bigger than length.
Also change places where bytesused is set directly with that function.
This help find/eliminate possible buffer overflow.

  media: replace setting of bytesused with vb2_set_plane_payload
  media: videobuf2: add WARN_ON if bytesused is bigger than buffer
    length
