CVE-2024-46711 Details
Description
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: fix ID 0 endp usage after multiple re-creations 'local_addr_used' and 'add_addr_accepted' are decremented for addresses not related to the initial subflow (ID0), because the source and destination addresses of the initial subflows are known from the beginning: they don't count as "additional local address being used" or "ADD_ADDR being accepted". It is then required not to increment them when the entrypoint used by the initial subflow is removed and re-added during a connection. Without this modification, this entrypoint cannot be removed and re-added more than once.
A vulnerability in the Linux kernel's Multipath TCP (MPTCP) implementation has been addressed. The issue arose because the 'local_addr_used' and 'add_addr_accepted' counters were incorrectly decremented for addresses associated with the initial subflow (ID 0) after the entry point was removed and re-added during a connection. This mismanagement could prevent the entry point from being re-added more than once, leading to potential disruptions in the MPTCP connection management.
Users can upgrade to the latest version of the Linux kernel 6.1 series, which includes the necessary fix. Instructions for upgrading can be found in the Debian LTS advisory DLA-4008-1.
