Name of the Vulnerable Software and Affected Versions NetworkManager versions prior to 1.30.0

Description The issue is related to incorrect handling of the match.path property setting and profile activation in NetworkManager, which can lead to a denial of service. This can cause NetworkManager to crash when the match.path property is set and a profile is activated, posing a threat to system availability.

Recommendations For versions prior to 1.30.0, update to version 1.30.0 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the match.path property to minimize the risk of crashing NetworkManager until a patch is applied.
