CVE-2024-56643: dccp: Fix memory leak in dccp_feat_change_recv

Published Dec 27, 2024

In the Linux kernel, the following vulnerability has been resolved:

dccp: Fix memory leak in dccpfeatchangerecv

If dccpfeatpushconfirm() fails after new value for SP feature was accepted without reconciliation ('entry == NULL' branch), memory allocated for that value with dccpfeatclonespval() is never freed.

Here is the kmemleak stack for this:
