Memory Leak in Linux Kernel Tsi148 Bridge

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: staging: vme_user: fix location monitor leak in tsi148 bridge tsi148_probe() allocates a location monitor resource and links it into tsi148_bridge->lm_resources. The probe error path frees this list, but tsi148_remove() only frees the dma, slave and master resource lists, so the location monitor resource is leaked on device unbind or module unload. Free the lm_resources list in tsi148_remove() as well, before tsi148_bridge is freed.

Executive Summary

This vulnerability in the Linux kernel involves a memory leak in the tsi148 bridge driver. When the device is unloaded or unbound, a location monitor resource allocated during initialization is not properly freed, causing a resource leak.

Detection Guidance

This vulnerability is specific to the Linux kernel's staging vme_user driver and the tsi148 bridge. Detection requires checking for kernel module usage and potential resource leaks in the tsi148 driver. Inspect loaded kernel modules and system logs for errors related to vme_user or tsi148.

Impact Analysis

The impact is primarily on system stability and resource management. Over time, repeated unloading or unbinding of the affected device could lead to memory exhaustion, causing performance degradation or system crashes.

Mitigation Strategies

Update the Linux kernel to a patched version that includes the fix for this vulnerability. If the tsi148 driver is not in use, consider unloading the vme_user module to prevent potential exploitation. Monitor system logs for any related errors after applying updates.
