Overview
CVE-2026-98285 is a known-severity vulnerability. It was published on October 6, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: vlan: fix bugs caused by switchdev deletion errors
Allowing switchdev to prevent vlan deletion and error out in __vlan_del
could cause multiple different issues - inconsistent state, memory leaks
when flushing, NULL pointer dereference on bridge error when flushing.
It doesn't make sense to allow it to stop __vlan_del, so log the error
and continue with software vlan deletion. This is also consistent with
8021q behaviour.
