Overview

CVE-2024-26839 is a medium-severity vulnerability. It was published on April 17, 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:

IB/hfi1: Fix a memleak in init_credit_return

When dma_alloc_coherent fails to allocate dd->cr_base[i].va,

init_credit_return should deallocate dd->cr_base and

dd->cr_base[i] that allocated before. Or those resources

would be never freed and a memleak is triggered.

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.
