Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: media: camss: Clean up received buffers on failed start of streaming It is required to return the received buffers, if streaming can not be started. For instance media_pipeline_start() may fail with EPIPE, if a link validation between entities is not passed, and in such a case a user gets a kernel warning: WARNING: CPU: 1 PID: 520 at drivers/media/common/videobuf2/videobuf2-core.c:1592 vb2_start_streaming+0xec/0x160 <snip> Call trace: vb2_start_streaming+0xec/0x160 vb2_core_streamon+0x9c/0x1a0 vb2_ioctl_streamon+0x68/0xbc v4l_streamon+0x30/0x3c __video_do_ioctl+0x184/0x3e0 video_usercopy+0x37c/0x7b0 video_ioctl2+0x24/0x40 v4l2_ioctl+0x4c/0x70 The fix is to correct the error path in video_start_streaming() of camss.
