Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix race condition when checking rpm_on When autosuspend is triggered, driver rpm_on flag is set to indicate that a suspend/resume is already in progress. However, when a userspace application submits a command during this narrow window, amdxdna_pm_resume_get() may incorrectly skip the resume operation because the rpm_on flag is still set. This results in commands being submitted while the device has not actually resumed, causing unexpected behavior. The set_dpm() is called by suspend/resume, it relied on rpm_on flag to avoid calling into rpm suspend/resume recursivly. So to fix this, remove the use of the rpm_on flag entirely. Instead, introduce aie2_pm_set_dpm() which explicitly resumes the device before invoking set_dpm(). With this change, set_dpm() is called directly inside the suspend or resume execution path. Otherwise, aie2_pm_set_dpm() is called.
