CVE-2025-68246 ksmbd: close accepted socket when per-IP limit rejects connection

In the Linux kernel, the following vulnerability has been resolved: ksmbd: close accepted socket when per-IP limit rejects connection When the per-IP connection limit is exceeded in ksmbdkthreadfn, the code sets ret = -EAGAIN and continues the accept loop without closing the just-accepted socket...

CVE-2025-68246

CVE-2025-68246 affects the ksmbd subsystem in the Linux kernel. When per-IP connection limits are exceeded in ksmbd_kthread_fn(), the code sets ret = -EAGAIN and continues the accept loop without closing the newly accepted socket, leaking one socket per rejected attempt from a single IP and enabl...
