It's a logic flaw in the kernel's crypto code (authencesn via AF_ALG and splice()) that allows a small write into the page cache, which can be used to tamper with a setuid binary like /usr/bin/su.
Think how bad this is going to be for shared environments like Kubernetes, CI runners, and cloud sandboxes, where it enables container escape and tenant-to-host compromise.
Found by Theori's Xint Code scanner, patched in the mainline kernel, and publicly disclosed on April 29, 2026; if you can't patch right away, the recommended workaround is to disable the algif_aead module.
become a generalist.
specialization makes you efficient. generalization makes you dangerous.
what it actually means:
• learn across domains → math, physics, software, economics, biology. patterns repeat across fields.
• connect ideas → innovation happens at the intersection, not inside silos.
• adapt fast → when one field shifts, you don’t collapse, you pivot.
• see systems → specialists see parts, generalists see the whole
• build end-to-end → from idea → design → implementation → delivery
the world rewards specialists in stable environments.
it rewards generalists when things are changing.
right now, everything is changing.
don’t just go deep.
go wide, then stack depth where it matters.
