CVE-2026-64016

A flaw was found in the Linux kernel's ksmbd component, which handles file sharing. When a durable network connection is re-established, an error in managing the lifetime of file objects can occur. This can lead to a situation where a file object is released from memory while still being referenced, creating a use-after-free vulnerability. An attacker could potentially exploit this to cause the system to crash (denial of service) or, in more severe cases, execute unauthorized code.
