high Nessus Plugin ID 191899

Synopsis

The remote Red Hat host is missing one or more security updates for kernel live patch module.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1253 advisory.

This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.

Security Fix(es):

* kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163)

* kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390)

* kernel: net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails (CVE-2023-3609)

* kernel: use after free in unix_stream_sendpage (CVE-2023-4622)

* kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)

* kernel: GSM multiplexing race condition leads to privilege escalation (CVE-2023-6546)

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.
