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.
The patch rolled out to LMDE yesterday (kernel v6.12.85), so I assume the number of affected systems has to be well on the wane by now.
(In that Debian is often well behind the cutting edge and Mint/LMDE is often a step or two behind that. Things are quicker than usual when there’s a showstopper kernel bug, but the lag factor is still there.)
