Overview

What is CVE-2026-98701?

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

wifi: mac80211: release mesh path quota on failed additions

Repeated failed or duplicate mesh path additions can exhaust MESH_MAX_MPATHS while the path table holds fewer paths, which stops new paths to reachable destinations from being created.

mesh_path_add() reserves a slot before allocating and inserting a path. If allocation fails, the function returns without releasing the slot.

If the rhashtable insertion reports an error or an existing destination, the function discards its candidate but retains the reservation. No new path is installed in any of these cases.

Release the reservation whenever the candidate is not installed.
