Description
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.
