CVE-2025-68750: usb: potential integer overflow in usbg_make_tpg()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Fixed version: Linux Linux 0861b9cb2ff519b7c5a3b1dd52a343e18c4efb24, 153874010354d050f62f8ae25cbb960c17633dc5, 358d5ba08f1609c34a054aed88c431844d09705a.

Low priority for now. Upgrade to Linux Linux 0861b9cb2ff519b7c5a3b1dd52a343e18c4efb24, 153874010354d050f62f8ae25cbb960c17633dc5, 358d5ba08f1609c34a054aed88c431844d09705a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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").
