CVE-2026-46292

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.12-1.1

Description A flaw exists in the generic power domain (genpd) core where the detach procedure for virtual devices is incomplete. When a device is attached via genpd dev pm attach by id(), the system calls pm runtime enable() for the registered virtual device. However, the genpd dev pm detach() function fails to call pm runtime disable(). This results in runtime power management remaining enabled for virtual devices after they are detached from their power domain. This inconsistency can lead to critical errors, such as a NULL pointer dereference in the genpd runtime suspend() function or the retention of unnecessary performance state votes for the device.

Recommendations Update to version 7.0.12-1.1.
