CVE-2023-53390 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drivers: base: dd: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.
A memory leak vulnerability has been identified in the Linux kernel's handling of debugfs_lookup() within the base driver. The issue arises because the result of debugfs_lookup() must be released with dput() to prevent memory leakage over time. The vulnerability is present in several versions of the Linux kernel. The recommended solution is to use debugfs_lookup_and_remove(), which automatically manages the necessary cleanup, thereby addressing the memory leak.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability. Instructions for downloading the patched version can be found in the Linux kernel Git repository.
