Unknown Unknown - Not Provided
Memory Leak in Linux Kernel octeon_ep Component Fixed

Publication date: 2026-02-14

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: octeon_ep: Fix memory leak in octep_device_setup() In octep_device_setup(), if octep_ctrl_net_init() fails, the function returns directly without unmapping the mapped resources and freeing the allocated configuration memory. Fix this by jumping to the unsupported_dev label, which performs the necessary cleanup. This aligns with the error handling logic of other paths in this function. Compile tested only. Issue found using a prototype static analysis tool and code review.

Executive Summary

This vulnerability exists in the Linux kernel within the octeon_ep driver, specifically in the octep_device_setup() function.

If the function octep_ctrl_net_init() fails during execution, octep_device_setup() returns immediately without properly cleaning up.

This means that mapped resources are not unmapped and allocated configuration memory is not freed, causing a memory leak.

The fix involves redirecting the error handling to a cleanup label (unsupported_dev) to ensure resources are properly released.

Impact Analysis

The vulnerability can lead to a memory leak in the Linux kernel when the octeon_ep driver fails to initialize properly.

Over time, this memory leak could cause increased memory usage, potentially degrading system performance or causing instability.

In environments where the octeon_ep driver is used, this could lead to resource exhaustion if the failure condition occurs repeatedly.
