CVE-2025-71303

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