So it’s certainly an interesting time to be a sysadmin or anyone who is currently working on a security team. W talked about the recent Dirty Frag Vulnerability only a short time ago and now we are seeing another serious potential attack vector on Linux systems. It definitely sounds bad, but like we talked about…

Linux has become one of the dominant players in serious 3D modeling. It now offers open source, high-performance tooling that rivals and in many use cases surpasses Windows workflows. More and more people are using Linux for 3D modeling, heck, even my kitchen contractor is using 3D modeling software now. We are going to look…

“Dirty Frag” is a Linux kernel local privilege escalation vulnerability that chains flaws in the kernel’s fragment handling (notably in xfrm‑ESP and RxRPC code paths) to let a local unprivileged attacker corrupt page‑cache fragments and modify in‑memory copies of protected files, enabling them to gain root access. It matters because it affects and is exploitable…
