CVE-2026-68378

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

Description A NULL pointer dereference occurs in the dpll msg add pin ref sync() function when a dpll pin is shared across multiple dpll device instances during the unregistration process, such as during driver module removal. This happens when a partner pin is unregistered from one device but remains registered with another, causing the dpll pin on dpll priv() function to return NULL. This NULL pointer is then passed to the driver's ref sync get() callback, leading to a system crash.

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