RHSA-2024:1836 - Moderate: kernel security, bug fix, and enhancement update

Synopsis

Moderate: kernel security, bug fix, and enhancement update

Type/Severity

Security Advisory Moderate

Topic

An update for kernel is now available for Red Hat Enterprise Linux 9.0 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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)
