Overview

CVE-2022-50138 is a medium-severity vulnerability. It was published on June 18, 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/qedr: Fix potential memory leak in __qedr_alloc_mr()

__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with

init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr"

is released while "mr->info.pbl_table" is not released, which will lead

to a memory leak.

We should release the "mr->info.pbl_table" with qedr_free_pbl() when error

occurs to fix the memory leak.

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.
