"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: account proxy paths against the mesh path limit\n\nProxy-path churn can drive the interface path counter negative and let\nlater mesh path additions exceed MESH_MAX_MPATHS.\n\nmesh_path_free_rcu() decrements the interface mpaths counter for entries\nfrom both the mesh and proxy path tables, but mpp_path_add() never\nreserves a slot in that counter. Removing or expiring a proxy path\ntherefore returns a slot that was never charged.\n\nmesh_path_add() uses the same counter to enforce MESH_MAX_MPATHS, so once\nit falls below the number of installed paths the limit no longer holds.\n\nReserve the shared quota before allocating a proxy path and release it on\nevery unsuccessful addition. Mesh and proxy paths now share one\n1024-entry budget, so mpp_path_add() can return -ENOSPC at that limit."
