CVE-2026-97540

net: usb: pegasus: don't rely on id table pointer arithmetic

State: Published
Severity: Not scored
Published: Sep 25, 2026
Updated: Oct 19, 2026
Reserved: Sep 24, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

net: usb: pegasus: don't rely on id table pointer arithmetic

The current code is broken when dynamic ID is involved; in such cases usb_device_id parameter of probe lives on the heap and the pointer arithmetic will get an index that is wildly out of bound. Instead of keeping a side table for additional information, use driver_info field of the usb_device_id.

The dynamic ID parsing code needs to be updated for this; convert it to just write to the reserved entry for dynamic ID and remove the weird loop.
