CVE-2023-53410 Details
Description
In the Linux kernel, the following vulnerability has been resolved: USB: ULPI: 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 USB ULPI (UTMI+ Low Pin Count) driver. The issue arises when the function 'debugfs_lookup()' is called without subsequently releasing the reference with 'dput()'. This oversight can lead to a gradual accumulation of unreleased memory. The vulnerability affects the stable versions of the Linux kernel.
The vulnerability has been addressed by modifying the ULPI driver to use 'debugfs_lookup_and_remove()', which automatically handles the reference management and prevents the memory leak. Users should upgrade to the patched version of the Linux kernel available in the Linux kernel stable tree.
