NVD Description

In the Linux kernel, the following vulnerability has been resolved:

debugfs: Fix lockdown check for mmap_prepare

Commit 651fdda8406d ("relay: update relay to use mmap_prepare") changed the mmap file operation to mmap_prepare for relayfs, but the lockdown check in debugfs was not updated accordingly.

This prevents debugfs from being locked down when the kernel is in integrity mode if a file uses mmap_prepare but not mmap.

Since the conversion to mmap_prepare across the kernel is not yet complete, update the lockdown check to look for both mmap and mmap_prepare to ensure comprehensive coverage.
