"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2024:1836 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * kernel: Out of boundary write in perf_read_group() as result of overflow a perf_event's read_size
    (CVE-2023-6931)

    * kernel: ext4: kernel bug in ext4_write_inline_data_end() (CVE-2021-33631)

    Bug Fix(es):

    * Performance drop on Broadcom bnxt_en nic after OCP upgrade from OCP 4.12 to OCP 4.13
    (4.18.0-372.32.1.el8_6.x86_64 to 5.14.0-284.32.1.el9_2.x86_64) (JIRA:RHEL-15379)

    * High latency with Matrox mgag200 (JIRA:RHEL-16558)

    * [regression][ext4][xfstests generic/094] Error reading from file with invalid argument (JIRA:RHEL-25435)

    * kernel: Out of boundary write in perf_read_group() as result of overflow a perf_event's read_size
    (JIRA:RHEL-21646)

    * xfs_growfs: XFS_IOC_FSGROWFSDATA xfsctl failed: No space left on device (RHEL9) (JIRA:RHEL-28688)

    * Memory corruption when using dm-crypt or dm-verity on RHEL-9 (JIRA:RHEL-26094)

    * kernel: ext4: kernel bug in ext4_write_inline_data_end() (JIRA:RHEL-26335)

    Enhancement(s):

    * [IBM 9.4 FEAT] Upgrade the qeth driver to latest from upstream, e.g. kernel 6.4 (JIRA:RHEL-25812)
