Vulnerability from fkie_nvd - Published: 2026-09-25 11:17 - Updated: 2026-09-28 06:16
Severity
Summary
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.
