Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel through 4.16.12 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact because sense buffers have different sizes at the CDROM layer and the SCSI layer, as demonstrated by a CDROMREADMODE2 ioctl call.
