Vulnerability from csaf_redhat - Published: 2024-03-27 00:15 - Updated: 2026-09-01 11:09Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Severity
Moderate
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 Moderate. 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: CIFS Filesystem Decryption Improper Input Validation Remote Code Execution Vulnerability in function receive_encrypted_standard of client (CVE-2024-0565)
* kernel: sched/membarrier: reduce the ability to hammer on sys_membarrier (CVE-2024-26602)
Bug Fix(es):
* kernel-rt: kernel: CIFS Filesystem Decryption Improper Input Validation Remote Code Execution Vulnerability in function receive_encrypted_standard of client (JIRA:RHEL-22083)
* kernel-rt: update RT source tree to the latest RHEL-9.2.z7 Batch (JIRA:RHEL-28866)
* [RHEL9.3 nightly] NMI panic sometimes fails to start the 2nd kernel for kdump (JIRA:RHEL-24448)
* kernel-rt: kernel: sched/membarrier: reduce the ability to hammer on sys_membarrier (JIRA:RHEL-26382)

An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
