high Nessus Plugin ID 192263

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1382 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):

* vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096)

* null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858)

* nfp: use-after-free in area_cache_get() (CVE-2022-3545)

* NULL pointer dereference in can_rcv_filter (CVE-2023-2166)

* Slab-out-of-bound read in compare_netdev_and_ip (CVE-2023-2176)

* out-of-bounds write in qfq_change_class function (CVE-2023-31436)

* NULL pointer dereference in vmxnet3_rq_cleanup() (CVE-2023-4459)

* net/sched: sch_qfq component can be exploited if in qfq_change_agg function happens qfq_enqueue overhead (CVE-2023-3611)

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

* inactive elements in nft_pipapo_walk (CVE-2023-6817)

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

Bug Fix(es):

* out-of-bounds write in qfq_change_class function (JIRA:RHEL-12700)

* vmxnet3: NULL pointer dereference in vmxnet3_rq_cleanup() (JIRA:RHEL-18192)

* refcount leak in ctnetlink_create_conntrack() (JIRA:RHEL-20302)

* inactive elements in nft_pipapo_walk (JIRA:RHEL-20703)

* ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (JIRA:RHEL-22099)

* update RT source tree to the latest RHEL-8.4.z Batch 23 (JIRA:RHEL-23825)

* null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (JIRA:RHEL-19023)

* Slab-out-of-bound read in compare_netdev_and_ip (JIRA:RHEL-19404)

* A flaw leading to a use-after-free in area_cache_get() (JIRA:RHEL-19530)

* vmxgfx: NULL pointer dereference in vmw_cmd_dx_define_query (JIRA:RHEL-22755)

* NULL pointer dereference in can_rcv_filter (JIRA:RHEL-19520)

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
