Description Adam Mariš 2018-05-28 13:14:35 UTC

The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel allows local users to cause a denial of service via a stack-based buffer overflow or possibly have unspecified other impact because sense buffers have different sizes at the CDROM layer and the SCSI layer.
