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

  - ext4: detect invalid INLINE_DATA + EXTENTS flag combination syzbot reported a BUG_ON in     ext4_es_cache_extent() when opening a verity file on a corrupted ext4 filesystem mounted without a     journal. The issue is that the filesystem has an inode with both the INLINE_DATA and EXTENTS flags set:
    EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15: comm syz.0.17: corrupted extent tree:
    lblk 0 < prev 66 Investigation revealed that the inode has both flags set: DEBUG: inode 15 - flag=1,     i_inline_off=164, has_inline=1, extents_flag=1 This is an invalid combination since an inode should have     either: - INLINE_DATA: data stored directly in the inode - EXTENTS: data stored in extent-mapped blocks     Having both flags causes ext4_has_inline_data() to return true, skipping extent tree validation in
    __ext4_iget(). The unvalidated out-of-order extents then trigger a BUG_ON in ext4_es_cache_extent() due to     integer underflow when calculating hole sizes. Fix this by detecting this invalid flag combination early     in ext4_iget() and rejecting the corrupted inode. (CVE-2025-40167)

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