GHSA-9FX8-XCMG-3R33

Vulnerability from github – Published: 2025-09-18 15:30 – Updated: 2025-12-11 15:30

Details

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.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
