CVE-2026-98223

The Linux kernel contains a vulnerability where Fault-around can map ready dropbehind folios without undergoing the standard page-cache lookup. Because a mapping represents a competing cached user, the system should retain the folio rather than forcibly unmapping it upon writeback completion. If ...
