Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992417 advisory.

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

    f2fs: fix to avoid use f2fs_bug_on() in f2fs_new_node_page()

    As Dipanjan Das <mail.dipanjan.das@gmail.com> reported, syzkaller     found a f2fs bug as below:

    NAT entry and nat bitmap can be inconsistent, e.g. one nid is free     in nat bitmap, and blkaddr in its NAT entry is not NULL_ADDR, it     may trigger BUG_ON() in f2fs_new_node_page(), fix it.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

An update of the linux package has been released.

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