In the Linux kernel, the following vulnerability has been resolved: dax/fsdev: clear vmemmapshift when binding static pgmap Clear pgmap-vmemmapshift for static DAX devices. When rebinding a static device from devicedax which may set vmemmapshift based on alignment to fsdevdax, the stale...

CVE-2026-93075: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: dax/fsdev: clear pgmap ops and owner on unbind fsdevdaxprobe sets pgmap-ops = &fsdevpagemapops and pgmap-owner = devdax, but nothing ever clears them. For a dynamic device the pgmap is devm-allocated and freed on unbind, so this ...
