CVE-2026-89473

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

Description A reference leak occurs in the bq25890 driver within the power supply subsystem. The bq25890 fw probe() function acquires a reference to a secondary charger via power supply get by name(), but this reference is not released during driver detach or when probe failures occur, including failures in bq25890 hw init() after bq25890 fw probe() has successfully returned. This can lead to resource exhaustion.

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