The remote Fedora 38 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-a8afe852a3 advisory.

    The 6.6.6 stable kernel update reverts the problematic cfg80211 patch that was brought into the 6.6.5     kernel

    ----

    The 6.6.5 stable kernel update contains a number of important fixes across the tree.

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

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

The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6680-3 advisory.

     discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not     properly handle certain memory allocation failure conditions, leading to a null pointer dereference     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-46343)

    It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to     a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2023-51779)

    It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux     kernel, leading to a use-after- free vulnerability. A local attacker could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2023-51782)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect     command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker     could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

    Jann Horn discovered that the io_uring subsystem in the Linux kernel contained an out-of-bounds access     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-6560)

    Dan Carpenter discovered that the netfilter subsystem in the Linux kernel did not store data in properly     sized memory locations. A local user could use this to cause a denial of service (system crash).
    (CVE-2024-0607)

    Supraja Sridhara, Benedict Schlter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the     Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit     emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service     (guest crash) or possibly execute arbitrary code. (CVE-2024-25744)

Tenable has extracted the preceding description block directly from the Ubuntu 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An out-of-bounds memory access flaw was found in the io_uring SQ/CQ rings functionality in the Linux     kernel. This issue could allow a local user to crash the system. (CVE-2023-6560)

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