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: fs/ntfs3: validate BOOT     sectors_per_clusters When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a shift value.
    Make sure that the shift value is not too large before using it (NTFS max cluster size is 2MB). Return
    -EVINVAL if it too large. This prevents negative shift values and shift values that are larger than the     field size. Prevents this UBSAN error: UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16 shift     exponent -192 is negative (CVE-2022-49553)

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

The version of kernel installed on the remote host is prior to 5.15.50-23.125. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-002 advisory.

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

    drm/plane: Move range check for format_count earlier (CVE-2021-47659)

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

    fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' (CVE-2021-47660)

    A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

    With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

    A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of     service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal     instruction in guest in the Intel CPU. (CVE-2022-1852)

    A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in     net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege     escalation issue. (CVE-2022-1966)

    A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal.
    This flaw allows a local attacker to crash the system and leads to a kernel information leak problem.
    (CVE-2022-1973)

    A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an     attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and     possibly to run code. (CVE-2022-2078)

    A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may     allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)

    A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors     may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)

    A flaw was found in hw. Incomplete cleanup in specific special register write operations for some     Intel Processors may allow an authenticated user to enable information disclosure via local access.
    (CVE-2022-21166)

    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

    An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer     overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point     registers. (CVE-2022-32981)

    rpmsg_virtio_add_ctrl_dev in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a     double free. (CVE-2022-34494)

    rpmsg_probe in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free.

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-131754 advisory.

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

    fs/ntfs3: validate BOOT sectors_per_clusters

    When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a     shift value.  Make sure that the shift value is not too large before using     it (NTFS max cluster size is 2MB).  Return -EVINVAL if it too large.

    This prevents negative shift values and shift values that are larger than     the field size.

    Prevents this UBSAN error:

     UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16      shift exponent -192 is negative

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