Published Jun 18, 2025CWE-416EPSS 0.18%

Overview

CVE-2022-50129 is a high-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, rated HIGH. 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/srpt: Fix a use-after-free

Change the LIO port members inside struct srpt_port from regular members

into pointers. Allocate the LIO port data structures from inside

srpt_make_tport() and free these from inside srpt_make_tport(). Keep

struct srpt_device as long as either an RDMA port or a LIO target port is

associated with it. This patch decouples the lifetime of struct srpt_port

(controlled by the RDMA core) and struct srpt_port_id (controlled by LIO).

This patch fixes the following KASAN complaint:

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.
