CVE-2026-46153

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