CVE-2025-68246 is a denial-of-service vulnerability in the Linux kernel's ksmbd component. In ksmbd_kthread_fn(), when a newly accepted connection exceeds the configured per-IP connection limit, the code returns an -EAGAIN condition and continues the accept loop without closing the just-accepted client socket. This causes one socket to be leaked for each rejected connection attempt from the same source IP. An attacker can repeatedly trigger this path remotely to accumulate leaked sockets and exhaust kernel or service resources, degrading or disrupting SMB service availability.

5 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
A socket resource leak in the Linux kernel's ksmbd SMB server permits remote denial of service. Connections rejected after exceeding the per-IP limit leave accepted sockets open, allowing repeated attempts to exhaust resources. The advisory assigns a CVSS v3 base score of 7.5; the fix closes the accepted socket before continuing the accept loop.
A vulnerability in ksmbd involving remote socket leakage that allows a client to consume resources and degrade service.
