Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
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):
* kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)
* kernel: sctp: fail if no bound addresses can be used for a given scope (CVE-2023-1074)
* kernel: NULL pointer dereference in nvmet_tcp_build_iovec (CVE-2023-6356)
* kernel: NULL pointer dereference in nvmet_tcp_execute_request (CVE-2023-6535)
* kernel: NULL pointer dereference in __nvmet_req_complete (CVE-2023-6536)
* kernel: Out-Of-Bounds Read vulnerability in smbCalcSize (CVE-2023-6606)
* kernel: OOB Access in smb2_dump_detail (CVE-2023-6610)
* kernel: use-after-free in IPv4 IGMP (CVE-2023-6932)
* kernel: refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)
* kernel: drivers/usb/storage/ene_ub6250.c (CVE-2023-45862)

"text": "This vulnerability poses a moderate severity risk due to its potential to trigger a use-after-free issue when processing IGMPv2 query packets under specific conditions. An attacker could exploit this flaw by continuously sending crafted IGMPv2 query packets to a vulnerable system, causing a reference count underflow in the multicast group list management. Subsequently, this could lead to a use-after-free scenario, potentially resulting in a denial-of-service condition or other adverse effects. While exploitation requires specific configurations and continuous packet transmission, the impact could be significant, warranting attention and remediation to prevent potential exploitation and system instability.",

This can be done by a blacklist mechanism which will ensure the driver is not loaded at boot time.\n~~~\nHow do I blacklist a kernel module to prevent it from loading automatically?\nhttps://access.redhat.com/solutions/41278 \n~~~",
