CVE-2024-46711: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 6.0, before 6.1.109 (fixed in 6.1.109); from 6.2, before 6.6.49 (fixed in 6.6.49); from 6.7, before 6.10.8 (fixed in 6.10.8); version 6.11 only
