Description
In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix memory leak in get_file_all_info() In get_file_all_info(), if vfs_getattr() fails, the function returns immediately without freeing the allocated filename, leading to a memory leak. Fix this by freeing the filename before returning in this error case.

Mitigation Strategies

To mitigate this vulnerability, update the Linux kernel to a version where the ksmbd get_file_all_info() memory leak has been fixed. This involves applying the patch that frees the allocated filename when vfs_getattr() fails. Until the update is applied, monitor for unusual memory usage in ksmbd processes as a precaution.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's ksmbd component within the get_file_all_info() function. Specifically, if the vfs_getattr() call fails, the function returns immediately without freeing the allocated filename memory, causing a memory leak. The fix involves freeing the filename before returning in this error case.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion if exploited repeatedly. This could affect system stability and reliability.
