The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3708 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 vulnerability in the perf_group_detach function of the Linux Kernel Performance     Events (CVE-2023-2235)

    * kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege     escalation (CVE-2023-32233)

    * Kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002)

    * kernel: OOB access in the Linux kernel's XFS subsystem (CVE-2023-2124)

    * kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer() (CVE-2023-2194)

    * kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference     (CVE-2023-28466)

    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):

    * [RT] Single Node Openshift cluster becomes unreachable after running less than 2 hours (BZ#2186853)

    * kernel-rt: update RT source tree to the latest RHEL-9.2.z1 Batch (BZ#2188313)
