CVE-2026-98756

A flaw was found in the Linux kernel's Cadence USB3 driver. A local user could exploit this flaw to cause a Denial of Service (DoS) by crashing the system. During device discovery of a multi-function Cadence USBSS Peripheral Component Interconnect (PCI) device, the driver attempts to access shared data before the primary function has finished initializing it. This timing issue triggers a NULL pointer dereference, resulting in an unhandled kernel crash.
