Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2022-50312 is a vulnerability discovered in the Linux kernel, specifically affecting the drivers/serial/jsm component. The vulnerability was disclosed on September 15, 2025, and involves a memory leak issue in the probe function where the error path needs proper unwinding instead of returning directly (NVD).

Technical details

The vulnerability exists in the Linux kernel's JSM serial driver where improper error handling in the probe function leads to memory leaks. The issue occurs when the error path returns directly instead of properly unwinding allocated resources (NVD). As of the disclosure date, no CVSS score has been assigned to this vulnerability.

Impact

The vulnerability could result in memory leaks in the Linux kernel's serial driver component, potentially leading to resource exhaustion over time (NVD).

Mitigation and workarounds

Multiple Linux distributions have released patches to address this vulnerability. Ubuntu has provided fixes across several versions: Ubuntu 22.04 LTS (5.15.0-60.66), Ubuntu 20.04 LTS (5.4.0-139.156), and Ubuntu 18.04 LTS (4.15.0-204.215) (Ubuntu).
