CVE-2026-31760

The CVE-2026-31760 issue affects the Linux kernel GPIB gpib: lpvo_usb driver, where the driver incorrectly retains references to USB devices during GPIB attach, causing a memory leak on disconnect. The root cause is not releasing those references after attaching, leading to resource retention. Th...

CVE-2026-31757

CVE-2026-31757 affects the Linux kernel USB subsystem (usbio). The issue is a memory leak where, if usb_submit_urb() fails during device probing (usbio_probe()), the previously allocated URB is not freed. The fix directs control flow to an error path (err_free_urb) to properly release the URB and...
