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.
