CVE-2025-68191

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contained an issue where the udp tunnel nic register() function incorrectly used netdev WARN() for non-critical error reporting. netdev WARN() includes a backtrace, which is unnecessary for normal runtime errors like memory allocation failures (using kzalloc() or udp tunnel nic alloc()). The issue has been addressed by replacing netdev WARN() with netdev warn(), which is more appropriate for these types of operational failures.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
