Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0724 advisory.

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

Security Fix(es):

* kernel: use-after-free in sch_qfq network scheduler (CVE-2023-4921)

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

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

* kernel: use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640)

* kernel: improper input validation may lead to privilege escalation (CVE-2021-4204)

* kernel: memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002)

* kernel: eBPF verification flaw (CVE-2021-34866)

* kernel: smb2_ioctl_query_info NULL pointer dereference (CVE-2022-0168)

* kernel: Linux ebpf logic vulnerability leads to critical memory read and write gaining root privileges (CVE-2022-0500)

* kernel: NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617)

* kernel: possible race condition in drivers/tty/tty_buffers.c (CVE-2022-1462)

* kernel: buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078)

* kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)

* kernel: netfilter: nf_conntrack_irc message handling issue (CVE-2022-2663)

* kernel: memory leak in ipv6_renew_options() (CVE-2022-3524)

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

* kernel: data races around icsk->icsk_af_ops in do_ipv6_setsockopt (CVE-2022-3566)

* kernel: Rate limit overflow messages in r8152 in intr_callback (CVE-2022-3594)

* kernel: memory leak in l2cap_recv_acldata of the file net/bluetooth/l2cap_core.c (CVE-2022-3619)

* kernel: denial of service in follow_page_pte in mm/gup.c due to poisoned pte entry (CVE-2022-3623)

* kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed (CVE-2022-3707)

* kernel: possible to use the debugger to write zero into a location of choice (CVE-2022-21499)

* kernel: local privileges escalation in kernel/bpf/verifier.c (CVE-2022-23222)

* kernel: Executable Space Protection Bypass (CVE-2022-25265)

* kernel: double free in usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c (CVE-2022-28388)

* kernel: double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)

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-2024:0724.
