Memory Leak in Linux Kernel ipw2100 Driver

Publication date: 2026-08-10

Last updated on: 2026-08-10

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ipw2100: fix potential memory leak in ipw2100_pci_init_one() The memory allocated in the ipw2100_alloc_device() function is not freed in some of the error paths in ipw2100_pci_init_one(). Fix that by converting the direct return into a goto to the error path return. The error path when pci_enable_device() fails cannot jump to fail, since at this point priv is not set, so perform error handling inline.

Executive Summary

This is a memory leak vulnerability in the Linux kernel's ipw2100 Wi-Fi driver. The issue occurs in the ipw2100_pci_init_one() function where memory allocated by ipw2100_alloc_device() is not properly freed in certain error paths. The fix converts a direct return into a goto statement to ensure proper cleanup.

Detection Guidance

This vulnerability is specific to the Linux kernel's ipw2100 Wi-Fi driver and involves a potential memory leak during initialization. Detection requires checking if the affected driver is loaded and examining kernel logs for related errors.

Impact Analysis

This vulnerability could lead to memory leaks when the ipw2100 Wi-Fi driver fails to initialize properly. Over time, this may cause system instability or reduced performance due to gradual exhaustion of available memory.

Mitigation Strategies

Update the Linux kernel to a patched version where this issue is resolved. If using a vulnerable kernel, avoid loading the ipw2100 driver or disable the affected hardware until patched.
