CVE-2022-50161
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2022-50161 is a vulnerability discovered in the Linux kernel's MTD (Memory Technology Device) maps subsystem. The issue was identified in the offlashprobeversatile function where offindmatchingnodeandmatch() returns a node pointer with an incremented reference count that is not properly released (NVD).

Technical details

The vulnerability occurs specifically in the MTD maps subsystem of the Linux kernel. The technical issue involves a reference count leak in the offlashprobeversatile function. When offindmatchingnodeandmatch() is called, it returns a node pointer with an incremented reference count, but the code fails to properly call ofnodeput() to release the reference when it's no longer needed (Wiz).

Impact

The reference count leak can potentially lead to memory resource exhaustion over time as unreleased references accumulate in the system (Wiz).

Mitigation and workarounds

The vulnerability has been addressed by adding the missing ofnodeput() call to properly release the reference count when the node pointer is no longer needed (Wiz).
