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

  - PCI/proc: Use file_ns_capable() when checking config space read access proc_bus_pci_read() decides how     much of the config space is readable based on capable(CAP_SYS_ADMIN), which checks the credentials of the     task calling read(), not the credentials of the process that opened the file. The sysfs equivalent,     pci_read_config(), has checked the credentials of the opening process since commit de139a339395 (pci:
    check caps from sysfs file open to read device dependent config space), so a privileged process can open     the config space file and pass the file descriptor to an unprivileged process (for example, a process     running a KVM guest with an assigned device), which can then read the entire config space. The check was     subsequently routed through the LSM framework in commit 47970b1b2aa6 (pci: use security_capable() when     checking capablities during config space read) and converted to the dedicated helper in commit     ab0fa82b2df9 (pci-sysfs: use proper file capability helper function). Thus, the two interfaces check the     same capability against different credentials. Checking the credentials of the task calling read() makes     the outcome depend on who reads rather than who opened, so the restriction is bypassed whenever a more     privileged process reads through the descriptor. Checking the credentials recorded in file->f_cred settles     the decision at open() time and ties it to the file, where it cannot change with the caller. Use     file_ns_capable() to check CAP_SYS_ADMIN against the credentials in effect when the file was opened,     bringing the procfs interface in line with the sysfs behaviour. As a result, a file descriptor opened by a     privileged process and passed to an unprivileged one now allows the entire config space to be read through     procfs, matching sysfs. (CVE-2026-93206)

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