High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions X.Org and Xwayland (affected versions not specified)
Description A use-after-free flaw was found in the software. The issue occurs when changing an alarm, where the values of the change mask are evaluated one after the other. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
