Description OSIDB Bzimport 2026-09-17 18:04:39 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: bridge: arp/nd proxy: fix reading neigh ha

Currently neigh ha address is read directly, but that can result in
torn/partial reads if the neigh is being updated. Use neigh_ha_snapshot
to take a stable snapshot of the address.
