Fragnesia Made Public as Latest Linux Local Privilege Escalation Vulnerability (phoronix.com)

Lots of privilege escalations these days. But are there that many multiuser Linux systems nowadays ? I'm under the impression the whole landscape is either servers or single-user desktops (and ofc Android phones).

Sounds like this one is in the same kernel modules as dirtyfrag, so the existing mitigations (if in place) are sufficient.

At what point do we all start rolling our own microkernels? This is kind of getting silly now... 4 now in the past month?

UnRAID has released two point upgrades in the past two weeks because the previous AI-found vulnerabilities. Here we go again!

The primary source, which says keep the dirtyfrag mitigations in place, is https://github.com/v12-security/pocs/tree/main/fragnesia
