Introducing the Frag Gap
(CVE-2026-53362/CVE-2026-53366)!

Full details are written up in both EN and KO at https://t.co/sQZhd5gioD

If you're curious about the code, just checking out https://t.co/n70dTMdH3s is enough.

We've got a few more fun bugs, and we'll post them as we find the time. This is just the Hitchhiker's Guide to the Linux Kernel.

Don't Kernel Panic!
