The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:1263 advisory.

    The redhat-virtualization-host packages provide the Red Hat Virtualization Host.
    These packages include redhat-release-virtualization-host. Red Hat     Virtualization Hosts (RHVH) are installed using a special build of Red Hat     Enterprise Linux with only the packages required to host virtual machines.
    RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative     tasks.

    Security Fix(es):

    * kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

    * kernel: use-after-free in RDMA listen() (CVE-2021-4028)

    * kernel: fget: check that the fd still exists after getting a ref to it (CVE-2021-4083)

    * kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL (CVE-2021-4155)

    * aide: heap-based buffer overflow on outputs larger than B64_BUF (CVE-2021-45417)

    * kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

    * openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778)

    * kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

    * cyrus-sasl: failure to properly escape SQL input allows an attacker to execute arbitrary SQL commands     (CVE-2022-24407)

    * expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution (CVE-2022-25235)

    * expat: Namespace-separator characters in xmlns[:prefix] attribute values can lead to arbitrary code     execution (CVE-2022-25236)

    * expat: Integer overflow in storeRawNames() (CVE-2022-25315)

    Bug Fix(es):

    * RHV-H has been rebased on RHEL-7.9.z #13 (BZ#2048409)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
