Description
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: tag_8021q: avoid leaking ctx on dsa_tag_8021q_register() error path
If dsa_tag_8021q_setup() fails, for example due to the inability of the
device to install a VLAN, the tag_8021q context of the switch will leak.
Make sure it is freed on the error path.
