Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 Linux 核心中，已解決下列弱點： ksmbd: fix reference count leak in smb_check_perm_dacl() The issue happens in a specific path in smb_check_perm_dacl(). When id and uid have the same value, the function simply jumps out of the loop without decrementing the reference count of the object posix_acls, which is increased by get_acl() earlier. This may result in memory leaks. Fix it by decreasing the reference count of posix_acls before jumping to label check_access_bits.
    (CVE-2022-49366)

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

  - In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix reference count leak in     smb_check_perm_dacl() The issue happens in a specific path in smb_check_perm_dacl(). When id and uid     have the same value, the function simply jumps out of the loop without decrementing the reference count of     the object posix_acls, which is increased by get_acl() earlier. This may result in memory leaks. Fix it     by decreasing the reference count of posix_acls before jumping to label check_access_bits.
    (CVE-2022-49366)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011320 advisory.

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

    ksmbd: fix reference count leak in smb_check_perm_dacl()

    The issue happens in a specific path in smb_check_perm_dacl(). When     id and uid have the same value, the function simply jumps out of     the loop without decrementing the reference count of the object     posix_acls, which is increased by get_acl() earlier. This may     result in memory leaks.

    Fix it by decreasing the reference count of posix_acls before     jumping to label check_access_bits.

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.
