Summary

Red Hat Security Advisory: kernel-rt security update

Notes

Topic

An update for kernel-rt is now available for Red Hat Enterprise Linux 8.2 Telecommunications Update Service. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390) * net/sched: sch_qfq component can be exploited if in qfq_change_agg function happens qfq_enqueue overhead (CVE-2023-3611) * net/sched: sch_hfsc UAF (CVE-2023-4623) * use-after-free in sch_qfq network scheduler (CVE-2023-4921) * use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178) * inactive elements in nft_pipapo_walk (CVE-2023-6817) * out-of-bounds write in qfq_change_class function (CVE-2023-31436) * nf_tables: stack-out-of-bounds-read in nft_byteorder_eval() (CVE-2023-35001) * IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871) * ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646) * nfp: use-after-free in area_cache_get() (CVE-2022-3545) * vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096) * Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982) * null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858) * fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment (CVE-2023-38409) * use-after-free in l2cap_sock_release in net/bluetooth/l2cap_sock.c (CVE-2023-40283) 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.

A successful exploit needs necessary privileges (CAP_NET_ADMIN) and direct, local access. A local user in RHCOS is already a root with full permissions, hence existence of this vulnerability does not bring any value from the potential attacker perspective. From the OpenShift containers perspective, this vulnerability cannot be exploited as in OpenShift the cluster processes on the node are namespaced, which means that switching the namespace in the running OpenShift container will not bring necessary capabilities.\nThis means that for OpenShift, the impact of this vulnerability is Low.\n\nSimilar to the CVE-2023-32233 vulnerability, this has been explained in the following blog post as an example of a \"Container escape vulnerability\":\nhttps://www.redhat.com/en/blog/containers-vulnerability-risk-assessment",

A successful exploit needs necessary privileges (CAP_NET_ADMIN) and direct, local access. A local user in RHCOS is already a root with full permissions, hence existence of this vulnerability does not bring any value from the potential attacker perspective. From the OpenShift containers perspective, this vulnerability cannot be exploited as in OpenShift the cluster processes on the node are namespaced, which means that switching the namespace in the running OpenShift container will not bring necessary capabilities.\nThis means that for OpenShift, the impact of this vulnerability is Low.\n\nSimilar to the CVE-2023-32233 vulnerability, this has been explained in the following blog post as an example of a \"Container escape vulnerability\":\nhttps://www.redhat.com/en/blog/containers-vulnerability-risk-assessment",

cve-2023-3390

Vulnerability from cvelistv5

Published

2023-06-28 20:02

Modified

2024-08-02 06:55

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.

cve-2023-4921

Vulnerability from cvelistv5

Published

2023-09-12 19:45

Modified

2024-08-02 07:44

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8.

cve-2023-3611

Vulnerability from cvelistv5

Published

2023-07-21 20:49

Modified

2024-09-27 13:43

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.

cve-2023-6817

Vulnerability from cvelistv5

Published

2023-12-18 14:37

Modified

2024-08-02 08:42

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free. We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.

cve-2023-38409

Vulnerability from cvelistv5

Published

2023-07-17 00:00

Modified

Severity ?

Summary

An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info).

Vulnerability from cvelistv5

Published

2023-09-06 13:56

Modified

2024-08-02 07:31

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f.
