Description
In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom: Fix leak when custom dump_segments addition fails Free allocated minidump_region 'name' in qcom_add_minidump_segments() when failing before adding the region to 'dump_segments'. Otherwise, the 'name' is not tracked and is never freed by qcom_minidump_cleanup(). Return error when adding to 'dump_segments' fails.

Executive Summary

This vulnerability in the Linux kernel involves a memory leak in the Qualcomm remote processor (remoteproc) subsystem. When a custom dump_segments function fails to add a minidump region, the allocated memory for the region's name is not freed, leading to a resource leak. The system fails to properly track and clean up this memory, which could accumulate over time.

Detection Guidance

This vulnerability is specific to the Linux kernel's remoteproc subsystem for Qualcomm devices. Detection requires checking for memory leaks in the qcom_add_minidump_segments() function. Monitor system logs for remoteproc-related errors or memory allocation failures. Use kernel debugging tools like ftrace or perf to track memory allocations in the remoteproc module.

Impact Analysis

This vulnerability may cause system instability or performance degradation due to memory leaks. If exploited repeatedly, it could lead to denial-of-service conditions by exhausting available memory. Systems using Qualcomm remote processors are primarily affected.

Mitigation Strategies

Apply the latest kernel patches from your Linux distribution that address this specific remoteproc memory leak issue. If patches are unavailable, consider disabling the affected remoteproc functionality if not required. Monitor system memory usage for leaks after applying fixes.
