Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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)

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.

Solution

Update the affected packages.
