CVE-2026-93075 dax/fsdev: clear pgmap ops and owner on unbind

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 ...

CVE-2026-93073

This TOCTOU race condition affects the Linux kernel DAX subsystem in the dax_holder_notify_failure() function. The function reads dax_dev->holder_ops twice without READ_ONCE()—once for a NULL check and once for the indirect notify_failure() call. A concurrent fs_put_dax() can clear holder_ops ...
