CVE-2026-89739

CVE-2026-89739 is a use-after-free in the Linux kernel 's USB DWC3 gadget driver. When a USB gadget is removed, dwc3_gadget_free_endpoints frees endpoint memory via kfree(dep), but a delayed work (dwc3_nostream_work) previously queued on system_percpu_wq during a DEPEVT_STREAM_NOSTREAM event may ...
