The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - virt/coco/sev-guest: Double-buffer messages The encryption algorithms read and write directly to shared     unencrypted memory, which may leak information as well as permit the host to tamper with the message     integrity. Instead, copy whole messages in or out as needed before doing any computation on them.
    (CVE-2023-53769)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-184 advisory.

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

    In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)
