Overview

CVE-2022-49208 is a medium-severity vulnerability. It was published on February 26, 2025 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:

RDMA/irdma: Prevent some integer underflows

My static checker complains that:

drivers/infiniband/hw/irdma/ctrl.c:3605 irdma_sc_ceq_init()

warn: can subtract underflow 'info->dev->hmc_fpm_misc.max_ceqs'?

It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware

in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could

be zero. Even if we trust the firmware, it's easy enough to change the

condition just as a hardenning measure.

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.
