CVE-2026-43422
The CVE-2026-43422 entry concerns the Linux kernel USB legacy NCM driver. The vulnerability stems from deferred net_device allocation in gncm_bind, where a NULL pointer dereference could occur when accessing the net_device before it is fully instantiated. The fix, described in the connected repor...
CVE-2026-43423
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: Fix atomic context locking issue The ncmsetalt function was holding a mutex to protect against races with configfs, which invokes the might-sleep function inside an atomic context. Remove the struct netdevice...
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...

CVE-2026-43421
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: Fix netdevice lifecycle with devicemove The network device outlived its parent gadget device during disconnection, resulting in dangling sysfs links and null pointer dereference problems. A prior attempt to sol...
CVE-2026-43421
The CVE affects the Linux kernel USB gadget for Network Control Model (NCM) where a net_device could outlive its parent gadget during disconnection, causing dangling sysfs links and potential null dereference. The root cause was lifecycle mismanagement of net_device during USB bind/unbind, addres...

CVE-2026-43375
In the Linux kernel, the following vulnerability has been resolved: net: mctp: fix device leak on probe failure Driver core holds a reference to the USB interface and its parent USB device while the interface is bound to a driver and there is no need to take additional references unless the...
CVE-2026-43375
CVE-2026-43375 concerns the Linux kernel in the MCTP path. A leak occurs during probe failures because the driver saves a reference to the USB device but fails to release it on error paths. The fix drops the redundant device reference to prevent memory leaks when the probe fails, simplifying driv...
