CVE-2026-43423

Concrete details show a Linux kernel issue in the usb gadget f_ncm driver: the ncm_set_alt function held a mutex to guard configfs races and invoked may_sleep in an atomic context, enabling a potential sleep path. The fix removes a struct net_device pointer from f_ncm_opts and introduces a new bo...
