CVE-2024-46711

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mptcp: pm: fix ID 0 endp usage after multiple re-creations<br /> <br /> &amp;#39;local_addr_used&amp;#39; and &amp;#39;add_addr_accepted&amp;#39; are decremented for addresses<br /> not related to the initial subflow (ID0), because the source and<br /> destination addresses of the initial subflows are known from the<br /> beginning: they don&amp;#39;t count as "additional local address being used" or<br /> "ADD_ADDR being accepted".<br /> <br /> It is then required not to increment them when the entrypoint used by<br /> the initial subflow is removed and re-added during a connection. Without<br /> this modification, this entrypoint cannot be removed and re-added more<br /> than once.
