In the Linux kernel, the following vulnerability has been resolved: usb: potential integer overflow in usbg_make_tpg() The variable tpgt in usbg_make_tpg() is defined as unsigned long and is assigned to tpgt->tport_tpgt, which is defined as u16. This may cause an integer overflow when tpgt is greater than USHRT_MAX (65535). I haven't tried to trigger it myself, but it is possible to trigger it by calling usbg_make_tpg() with a large value for tpgt. I modified the type of tpgt to match tpgt->tport_tpgt and adjusted the relevant code accordingly. This patch is similar to commit 59c816c1f24d ("vhost/scsi: potential memory corruption").

The CVE record on cve.org NVD's entry
The CVE record is authoritative. Products marked “from the name” were identified from the CNA's free-text names, not a CPE, and are matched less certainly. This product uses the NVD API but is not endorsed or certified by the NVD.
