Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/handshake: restore destructor on submit failure<br /> <br /> handshake_req_submit() replaces sk-&gt;sk_destruct but never restores it when<br /> submission fails before the request is hashed. handshake_sk_destruct() then<br /> returns early and the original destructor never runs, leaking the socket.<br /> Restore sk_destruct on the error path.
