  - ovl: check access to copy_file_range source with src mounter creds Commit 5dae222a5ff0c (vfs: allow     copy_file_range to copy across devices) allowed filesystems that implement the copy_file_range() f_op to     decide if they want to access cross-sb copy from/to the same fs type. The same commit added checks to     verify same sb copy for filesystems that implement ->copy_file_range() and do not support cross-sb copy at     the time, namely, to ceph, fuse and nfs. The two remaining fs which implement ->copy_file_range(), cifs     and overlayfs started to support cross-sb copy from this time. While overlayfs does support cross-sb copy     when the two underlying files are on the same base fs, the copy operation on the two real files from two     different overalyfs filesystems is performed with the mounter creds of the destination overlayfs and the     read permission access hook for the source file was called with the wrong creds. This could cause either     deny of access to copy which would otherwise be allowed (e.g. with splice) or allow read access to file     which would otherwise be denied. Fix the latter case by explicitly verifying read access to source file     with the source overlayfs mounter creds. The former case remains a quirk of cross-sb overlayfs copy, but     userspace could fall back to regular copy so no harm done. (CVE-2026-68448)

Note that Nessus relies on the presence of the package as reported by the vendor.
