The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6548-3 advisory.

    It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could     potentially use this to expose sensitive information. (CVE-2023-3006)

    It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling     device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker     could possibly use this to cause a denial of service (system crash). (CVE-2023-37453)

    Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some     attributes passed from userspace. A local attacker could use this to cause a denial of service (system     crash) or possibly expose sensitive information (kernel memory). (CVE-2023-39189)

    Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did not properly validate u32     packets content, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause     a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-39192)

    Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate SCTP     data, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information. (CVE-2023-39193)

    Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel did not     properly handle state filters, leading to an out- of-bounds read vulnerability. A privileged local     attacker could use this to cause a denial of service (system crash) or possibly expose sensitive     information. (CVE-2023-39194)

    Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket     buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference     vulnerability. A privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2023-42754)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly handle queue     initialization failures in certain situations, leading to a use-after-free vulnerability. A remote     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-5178)

    Budimir Markovic discovered that the perf subsystem in the Linux kernel did not properly handle event     groups, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-5717)

    It was discovered that the TLS subsystem in the Linux kernel did not properly perform cryptographic     operations in some situations, leading to a null pointer dereference vulnerability. A local attacker could     use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6176)
