This may cause an\ninteger overflow when tpgt is greater than USHRT_MAX (65535). I\nhaven't tried to trigger it myself, but it is possible to trigger it\nby calling usbg_make_tpg() with a large value for tpgt.\n\nI modified the type of tpgt to match tpgt->tport_tpgt and adjusted the\nrelevant code accordingly.\n\nThis patch is similar to commit 59c816c1f24d (\"vhost/scsi: potential\nmemory corruption\").\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
