TIPC: case study in proactive Linux hardening
If you needed a nice case study for a CTO presentation on how proactive Linux does work in real life scenarios, here;s one I’ve just found in my old commits searching for something entirely else - the CVE-2021-43267 published in 2021 in Linux tipc module.
