CVE-2026-43327

CVE-2026-43327 affects the Linux kernel USB dummy-hcd code. The race involves usb_gadget_udc_reset() being invoked with a NULL second argument (driver) due to a race between USB reset and driver unbind, enabling a potential crash. The root cause was that stop_activity() could drop and re-acquire ...
