Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - btrfs: tracepoints: get correct superblock from dentry in event btrfs_sync_file() If overlay is used on     top of btrfs, dentry->d_sb translates to overlay's super block and fsid assignment will lead to a crash.
    Use file_inode(file)->i_sb to always get btrfs_sb. (CVE-2026-43117)

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