A privilege escalation in the kernel's algif_aead module (CVSS 7.8) lets any unprivileged local user get root. Deterministic exploit. No race conditions, no kernel offsets. The flaw traces to a 2017 commit enabling page-cache pages in writable scatterlists. Patches haven't shipped from any major distro yet. Disable the algif_aead module now: echo "install algif_aead /bin/true" >> /etc/modprobe.d/disable-algif-aead.conf. Check back daily for vendor patches.
