  "description": "In the Linux kernel, the following vulnerability has been resolved:  debugfs: Fix lockdown check for mmap_prepare  Commit 651fdda8406d (\u0022relay: update relay to use mmap_prepare\u0022) changed the \u0060mmap\u0060 file operation to \u0060mmap_prepare\u0060 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 \u0060mmap_prepare\u0060 but not \u0060mmap\u0060.  Since the conversion to \u0060mmap_prepare\u0060 across the kernel is not yet complete, update the lockdown check to look for both \u0060mmap\u0060 and \u0060mmap_prepare\u0060 to ensure comprehensive coverage.",
