CVE-2024-26961
Description
A flaw was found in the Linux Kernel where resources are improperly managed in IEEE 802.15.4 networking, leading to a potential use-after-free issue, resulting in a denial of service.
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).

Red Hat CVSS v3 Score Explanation
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-459: Incomplete Cleanup vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.
The platform's ephemeral workloads, strict lifecycle management, and automated resource cleanup routines significantly reduce the likelihood that residual data would persist in a meaningful or exploitable state. Static code analysis and peer code review techniques are used to execute robust input validation and error-handling mechanisms to ensure all user inputs are thoroughly validated, reducing the risk of DoS attacks. Event logs are collected and processed for centralization, correlation, analysis, monitoring, reporting, alerting, and retention to detect anomalies and enforce cleanup procedures.

Technical Impact: Other; Read Application Data; Modify Application Data; DoS: Resource Consumption (Other)
It is possible to overflow the number of temporary files because directories typically have limits on the number of files allowed. This could create a denial of service problem.
