CVE-2022-50017:
Linux Debian vulnerability analysis and mitigation
Overview
In the Linux kernel, a vulnerability (CVE-2022-50017) was identified in the mips: cavium-octeon subsystem. The issue involves a missing ofnodeput() call in the octeon2usbclocks_start function. This vulnerability was disclosed on June 18, 2025 (NVD).
Technical details
The vulnerability stems from a reference counting issue where the ofnodeput() function is not called for the 'uctlnode' reference returned by ofgetparent(). This omission leads to a reference count leak bug, as the reference count that was increased by the ofget_parent() operation is not properly managed (NVD, Wiz).
Impact
The primary impact of this vulnerability is a memory leak in the kernel due to improper reference counting. If the affected code path is repeatedly executed, this could potentially lead to resource exhaustion over time (Wiz).
Mitigation and workarounds
The issue has been fixed by adding the missing ofnodeput() call for the reference 'uctlnode' returned by ofget_parent(). Users should update to a patched version of the Linux kernel that includes this fix (Wiz).
