The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6093-1 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)

    It was discovered that the Traffic-Control Index (TCINDEX) 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-2023-1281)

    Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon GPU devices did not properly     validate memory allocation in certain situations, leading to a null pointer dereference vulnerability. A     local attacker could use this to cause a denial of service (system crash). (CVE-2022-3108)

    It was discovered that the infrared transceiver USB driver did not properly handle USB control messages. A     local attacker with physical access could plug in a specially crafted USB device to cause a denial of     service (memory exhaustion). (CVE-2022-3903)

    Haowei Yan discovered that a race condition existed in the Layer 2 Tunneling Protocol (L2TP)     implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service     (system crash). (CVE-2022-4129)

    Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the do_prlimit() function in the     Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to     expose sensitive information (kernel memory). (CVE-2023-0458)

    It was discovered that the Human Interface Device (HID) support driver in the Linux kernel contained a     type confusion vulnerability in some situations. A local attacker could use this to cause a denial of     service (system crash). (CVE-2023-1073)

    It was discovered that a memory leak existed in the SCTP protocol implementation in the Linux kernel. A     local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2023-1074)

    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.
