CVE-2026-31431. 100% Reliable Linux LPE — no race, no per-distro offsets, page-cache write that bypasses on-disk file-integrity tools and crosses containers. Found by Xint Code.
Do you have a source for how often it happens or is this conjecture? I guess this would most often happen through supply chain attacks or physical access, the first not being all that common in my understanding and the latter not being a typical threat model for a home computer. But if you have a source explaining what actually happens, I would love to read it.

There are plenty of way to get a local unprivileged shell
For instance, if you are running a old version of cups someone could chain together several vulnerabilities to gain root on your system

Having a MAC like SELinux helps to mitigate this but you still should patch as soon as possible
