Overview

CVE-2024-38603 is a medium-severity vulnerability. It was published on June 19, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset()

pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action()

fails, the irq vector is not freed, which leads to a memory leak.

Replace the devm_add_action with devm_add_action_or_reset to ensure

the irq vector can be destroyed when it fails.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
