Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contained a flaw where duplicate registrations of pins were permitted. Specifically, the
dpll xa ref dpll add() and dpll xa ref pin add() functions allowed multiple registrations of the same pin on a device, leading to incorrect reference counting and potential issues during unregistration, such as warnings being triggered. The issue was addressed by modifying the registration logic to return -EEXIST if a matching registration was found, enforcing a strict "register once" policy.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
