GHSA-PGJ7-6V58-MXR9

Vulnerability from github – Published: 2025-09-16 15:32 – Updated: 2025-12-03 00:30

Details

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

misc: vmw_balloon: 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)
