CVE-2024-53922
Description
A flaw was found in the kernel's buffer queue driver. This vulnerability, caused by a missing length check, allows an attacker to trigger a Denial of Service (DoS) in the kernel.
Statement
A MODERATE severity flaw in the kernel affects Red Hat OpenShift Container Platform through the Red Hat Enterprise Linux CoreOS (RHCOS) container images. The vulnerability, reported by Samsung for the buffer queue driver in its Exynos Auto 8890, V7, V9, and V920 automotive processors, is caused by a missing length check. A local attacker with access to an affected system, requiring no privileges or user interaction, can exploit this flaw to trigger a denial of service in the kernel. Successful exploitation has a high impact on availability, a low impact on integrity, and no impact on confidentiality (CVSS 3.1 score 5.7, vector CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H), and exploitation requires local access with high attack complexity, which limits exposure. The affected OpenShift Container Platform streams are recorded as AFFECTED with resolution DEFER: because the impact is MODERATE and the CVSS score is below 7.0, no update trackers are filed for this flaw. The residual risk is that an attacker with local access to an affected node could crash or hang the kernel, causing a denial of service for that node. The Red Hat severity rating matches the upstream rating (CVSS 3.1 score 5.7 in both cases).
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
