I have a LinkSys WRT54GL v1.1 which currently has stock firmware version 4.30.7. I see that version 4.30.14 is available. The router works fine now, and the release notes look uninteresting except for one line in v4.30.9: "Resolves issue with Linux kernel vulnerability".
I have remote management turned off.
I'm aware of the 3rd-party firmwares but the stock firmware works fine for me at the moment, so I don't have an interest in those.
Is the status quo fine or should I upgrade the firmware? (It's a bit of a pain since the config has to be saved and reloaded, and obviously any mucking with firmware is risky.)

There's the old saying, if it works, don't fix it.
Is there any reason to upgrade? Do you need some feature that has been added to newer versions? Is your current version broken in some way?
You state no reason to upgrade, apart from the "kernel vulnerability". If you care about it, then you should read up on the details of that vulnerability to determine if it really affects your specific router. if it does, decide if you feel "at risk". Only then should you consider the upgrade. Karl's comment indicates that it's not a problem at all.
Personally, I wouldn't worry about it.
