CVE-2023-53412 Details
Description
In the Linux kernel, the following vulnerability has been resolved: USB: gadget: bcm63xx_udc: 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 gadget component, specifically within the bcm63xx_udc driver. This issue arises when the debugfs_lookup() function is called without subsequently releasing the reference with dput(), leading to a gradual increase in memory usage. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed by modifying the code to use debugfs_lookup_and_remove(), which automatically handles the reference management and prevents the memory leak.
