CVE-2022-50194:
Linux Kernel vulnerability analysis and mitigation
Overview
A vulnerability (CVE-2022-50194) was identified in the Linux kernel, specifically affecting the soc: qcom: aoss component in the qmpcoolingdevices_register functionality. The issue was disclosed on June 18, 2025 (NVD, Wiz).
Technical details
The vulnerability stems from a refcount leak in the foreachavailablechildofnode() loop implementation. Every iteration of the loop decrements the reference count of the previous node, but when breaking early from the loop, the code fails to explicitly call ofnode_put() on the child node, resulting in a reference count leak (NVD, Wiz).
Impact
The refcount leak in the kernel's memory management can potentially lead to resource exhaustion over time, which may affect system stability and performance (Wiz).
Mitigation and workarounds
The vulnerability has been resolved by adding the missing ofnodeput() call to properly manage reference counts when breaking early from the foreachavailablechildof_node() loop (NVD, Wiz).
