"According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function
    tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It
    is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this
    vulnerability. (CVE-2022-3566)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. This vulnerability affects
    the function vsock_connect of the file net/vmw_vsock/af_vsock.c. The manipulation leads to memory leak.
    The complexity of an attack is rather high. The exploitation appears to be difficult. It is recommended to
    apply a patch to fix this issue. VDB-211930 is the identifier assigned to this vulnerability.
    (CVE-2022-3629)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
