Vulnerability Name:

CVE-2018-11506 (CCN-143912)

Assigned:2018-05-21
Published:2018-05-21
Updated:2020-08-24
Summary: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.
