Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix use-after-free due to
 MST port state bypass syzbot reported[1] a use-after-free when deleting an expired fdb. It is due to a
 race condition between learning still happening and a port being deleted, after all its fdbs have been
 flushed. The port's state has been toggled to disabled so no learning should happen at that time, but if
 we have MST enabled, it will bypass the port's state, that together with VLAN filtering disabled can lead
 to fdb learning at a time when it shouldn't happen while the port is being deleted. VLAN filtering must be
 disabled because we flush the port VLANs when it's being deleted which will stop learning. This fix adds a
 check for the port's vlan group which is initialized to NULL when the port is getting deleted, that avoids
 the port state bypass. When MST is enabled there would be a minimal new overhead in the fast-path because
 the port's vlan group pointer is cache-hot. [1]
