RHEL 9 : kernel-rt (RHSA-2024:0725)

high Nessus Plugin ID 190109

Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0725 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: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)

* kernel: sctp: fail if no bound addresses can be used for a given scope (CVE-2023-1074)

* kernel: NULL pointer dereference in nvmet_tcp_build_iovec (CVE-2023-6356)

* kernel: NULL pointer dereference in nvmet_tcp_execute_request (CVE-2023-6535)

* kernel: NULL pointer dereference in __nvmet_req_complete (CVE-2023-6536)

* kernel: Out-Of-Bounds Read vulnerability in smbCalcSize (CVE-2023-6606)

* kernel: OOB Access in smb2_dump_detail (CVE-2023-6610)

* kernel: use-after-free in IPv4 IGMP (CVE-2023-6932)

* kernel: refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)

* kernel: drivers/usb/storage/ene_ub6250.c (CVE-2023-45862)

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.

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 RHEL kernel-rt package based on the guidance in RHSA-2024:0725.
