The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-347.el9 build changelog.

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

  - An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-     Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of     user-supplied sizes for the MSG_CRYPTO message type. (CVE-2021-43267)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)

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.

  - A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW)     breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain     write access to read-only memory mappings, increasing their privileges on the system. (CVE-2022-2590)

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

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6071-1 advisory.

    It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not     properly perform filter deactivation in some situations. A local attacker could possibly use this to gain     elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier     has been removed. (CVE-2023-1829)

    Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null     pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system     crash). (CVE-2023-0468)

    It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up     operation in some conditions. A local attacker could possibly use this to gain elevated privileges.
    (CVE-2023-0386)

    David Hildenbrand discovered that a race condition existed in the memory manager of the Linux kernel when     handling copy-on-write with shared memory pages. A local attacker could use this to cause a denial of     service (system crash) or execute arbitrary code. (CVE-2022-2590)

    It was discovered that the sound subsystem in the Linux kernel contained a race condition in some     situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3303)

    Gwnaun Jung discovered that the SFB packet scheduling implementation in the Linux kernel contained 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-2022-3586)

    It was discovered that a race condition existed in the EFI capsule loader driver 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-2022-40307)

    Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver in the Linux kernel     contained 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-2022-4095)

    It was discovered that the USB core subsystem in the Linux kernel did not properly handle nested reset     events. A local attacker with physical access could plug in a specially crafted USB device to cause a     denial of service (kernel deadlock). (CVE-2022-4662)

    It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file     system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory).
    (CVE-2023-1859)

    Kyle Zeng discovered that the ATM VC queuing discipline implementation in the Linux kernel contained a     type confusion vulnerability in some situations. An attacker could use this to cause a denial of service     (system crash). (CVE-2023-23455)

    Lianhui Tang discovered that the MPLS implementation in the Linux kernel did not properly handle certain     sysctl allocation failure conditions, leading to a double-free vulnerability. An attacker could use this     to cause a denial of service or possibly execute arbitrary code. (CVE-2023-26545)

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.
