Description

In the Linux kernel, the following vulnerability has been resolved: 8021q: delete cleared egress QoS mappings vlan_dev_set_egress_priority() currently keeps cleared egress priority mappings in the hash as tombstones. Repeated set/clear cycles with distinct skb priorities therefore accumulate mapping nodes until device teardown and leak memory. Delete mappings when vlan_prio is cleared instead of keeping tombstones. Now that the egress mapping lists are RCU protected, the node can be unlinked safely and freed after a grace period.
