Overview

CVE-2024-46711 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 13, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
