[kwlug-disc] Copy-Fail CVE-2026-31431

[CrankyOldBugger]

My Debian systems are up to 6.12.85, but my Raspi systems seem stuck at
6.12.75, despite patching several times since yesterday.  I wonder if
they're affected by the Ubuntu outage, maybe?  IIRC, Raspi is Debian based,
but I think they started out as Ubuntu based.
