CVE-2024-43864 Vulnerability Summary

CVE-2024-43864: In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix CT entry update leaks of modify header context The cited commit allocates a new modify header to replace the old one when updating CT entry. But if failed to allocate a new one, eg. exceed the max number firmware can support, modify header will be an error pointer that will trigger a panic when deallocating it. And the old modify header point is copied to old attr. When the old attr is freed, the old modify header is lost. Fix it by restoring the old attr to attr when failed to allocate a new modify header context. So when the CT entry is freed, the right modify header context will be freed. And the panic of accessing error pointer is also fixed.

Assessing the Risk of CVE-2024-43864

Access Complexity Graph

The exploitability of CVE-2024-43864 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2024-43864

No exploitability data is available for CVE-2024-43864.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2024-43864, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
