description |
On 2 occasions over the past week I have had full system crashes after running "wg-quick up wg0". On the terminal, the command does not complete (i.e. it does not return to the prompt), the fans on my laptop start whirring and the system gradually becomes unresponsive before my desktop crashes and the system becomes completely unresponsive. On both occasions I opened another window to run "top" to see what process was consuming resources but "top" never actually runs. On the second occasion I managed to run "dmesg" before the system crashed completely and saw multiple lines of text about a kernel oops and red-highlighted text about a null-pointer dereference.
I could reboot with "Alt-PrtScr_REISUB". On reboot I was confronted with the "system problem detected" dialog, but selecting the "report" option didn't seem to do anything. I have 2 reports in /var/crash from the last oops which I will attach to this report.
I cannot reproduce this on demand. Most of the time, wg-quick performs normally. On both occasions the laptop had recently woken from suspend, but invoking "wg-quick" after waking from suspend doesn't trigger it on demand. On the first occasion I was running with stock boot options. On the second, I was running with "mitigations=off" as an experiment.

I'm reporting this as a security bug due to the "Null pointer dereference" in the kernel, but don't know if that is relevant. I don't know how to access or send the old dmesg information, so please let me know how to access this or how to collect it if the crash recurs.
