UBUNTU-CVE-2025-40094

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: facm: Refactor bind path to use free After an bind/unbind cycle, the acm-notifyreq is left stale. If a subsequent bind fails, the unified error label attempts to free this stale request, leading to a NULL pointer...

CVE-2025-40095

The CVE refers to the Linux kernel USB gadget driver bug in f_rndis: after a bind/unbind cycle, rndis->notify_req becomes stale, and a subsequent bind failure could trigger a NULL pointer dereference when ep->ops->free_request is accessed. The root cause is in the bind path error handlin...
