Synopsis

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

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0432 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: xfrm_expand_policies() in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice (CVE-2022-36879)

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

* kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c (CVE-2023-1195)

* kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)

* kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race (CVE-2023-3567)

* kernel: use-after-free in netfilter: nf_tables (CVE-2023-3777)

* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)

* kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178)

* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)

* kernel: SEV-ES local priv escalation (CVE-2023-46813)

Bug Fix(es):

* RHEL 9 Hyper-V: Excessive hv_storvsc driver logging with srb_status SRB_STATUS_INTERNAL_ERROR (0x30)

* RHEL9.0 - s390/qeth: NET2016 - fix use-after-free in HSCI

* DM multipath showing failed path for an nvme-o-FC LUN when performing I/O operations

* XFS: sync to upstream v5.15

* AMDSERVER 9.4 Bug, Turin: Support larger microcode patches

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 package based on the guidance in RHSA-2024:0432.
