SUSE CVE-2011-3346

Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service guest crash via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has...

SUSE CVE-2018-12892

An issue was discovered in Xen 4.7 through 4.10.x. libxl fails to pass the readonly flag to qemu when setting up a SCSI disk, due to what was probably an erroneous merge conflict resolution. Malicious guest administrators or in some situations users may be able to write to supposedly read-only di...

Memory corruption

The biomapuseriov and biounmapuser functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bioaddpcpage function merges them into one, but the page reference is never dropped. This...
