CVE-2025-21746

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

Description A crash issue has been identified in the Linux kernel related to the synaptics input driver. When enabling a pass-through port, an interrupt may occur before the psmouse driver binds to the port. The synaptics sub-driver attempts to access the psmouse instance associated with the pass-through port, which may cause a crash if the psmouse instance has not been attached to the port yet. This issue is resolved by introducing open and close methods for the port and checking if the port is open before accessing the psmouse instance.

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