The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0622 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: use after free in eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

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

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

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

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

    * kernel: out of bounds write in hid-multitouch.c may lead to escalation of privilege (CVE-2020-0465)

    * kernel: double free in bluetooth subsystem when the HCI device initialization fails (CVE-2021-3564)

    * kernel: use-after-free in function hci_sock_bound_ioctl() (CVE-2021-3573)

    * kernel: possible use-after-free in bluetooth module (CVE-2021-3752)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * kernel-rt: update to the latest RHEL7.9.z12 source tree (BZ#2039101)

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3459-1 advisory.

  - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way     user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()     together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),     hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their     privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)

  - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
