Thanks for reporting this bug Claudio. As you might have expected I was not able to reproduce it locally. After checking the the core dump, we can see the crash happened when executing the sec_poll function in drivers/gamatronic.c file. I went through the upstream history of this file and I found some commits in the latest version (2.8.0) which might fix this issue for you.
Since version 2.8.0 is not even in Debian yet, I prepared a "dirty" package (removed some docs and manpages) and put it in this PPA: https://launchpad.net/~lucaskanashiro/+archive/ubuntu/nut Could you please try to test it and see if it fixes this issue for you? If yes, we can try to dig into those upstream commits and then find what is needed to SRU to jammy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1976307 Title: Stack smashing in gamatronic driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1976307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
