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

  - smb: client: bound dirent name against end of SMB response in cifs_filldir cifs_filldir() copies the entry     name out of an SMB1 TRANS2_FIND_FIRST / FIND_NEXT response using a length (de.namelen) supplied by the     server. The kmalloc'd SMB response buffer is bounded, but nothing checks that de.name + de.namelen still     lies inside that buffer before the eventual filldir64() -> verify_dirent_name() -> memchr() reads namelen     bytes. A hostile SMB1 server that returns an oversized FileNameLength in a directory entry therefore     causes memchr() to read past the end of the response slab buffer. Reachable from any user who can list a     directory on a CIFS mount served by an attacker-controlled server (getdents64() on the mounted directory):

This bug was discovered by Artiphishell's     vTriage pipeline, which generated a userspace reproducer (an emulated hostile SMB1 server plus a     getdents64() client) that reliably triggers the KASAN report on an unpatched kernel. The fix below was     drafted with the Claude coding assistant; a userspace reproducer is available on request. (CVE-2026-93787)

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