Linux Kernel Interconnect Exynos Node Leak Vulnerability in PM QoS Error Handling

A vulnerability in the Linux kernel's interconnect management for Exynos platforms has been addressed. The issue involved a memory leak of interconnect nodes during the probe phase when handling Power Management Quality of Service (PM QoS) errors. The vulnerability arose because the newly allocated interconnect node was not properly added to the provider before the PM QoS request was made, leading to a failure to free the node in error scenarios.

Impact

The vulnerability could lead to a memory leak, causing increased memory usage over time and potentially leading to memory exhaustion.
