GHSA-3J53-J44C-WP43

Vulnerability from github – Published: 2025-03-27 18:31 – Updated: 2025-04-15 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

kernel/irq/irqdomain.c: 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)
