CVE-2026-64230

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

Description An issue exists in the tps65219 regulator driver where the irq data.rdev variable remains uninitialized for all Interrupt Requests (IRQs). This occurs because a previous removal of the tps65219 get rdev by name() helper function also removed the assignment logic for irq data.rdev. Consequently, when the regulator notifier call chain() function is called from the tps65219 regulator irq handler() IRQ handler, it leads to undefined behavior and system crashes (Internal error: Oops).

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