In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Disable MMIO access during SMU Mode 1 reset During Mode 1 reset, the ASIC undergoes a reset cycle and becomes temporarily inaccessible via PCIe. Any attempt to access MMIO registers during this window (e.g., from interrupt handlers or other driver threads) can result in uncompleted PCIe transactions, leading to NMI panics or system hangs. To prevent this, set the flag to true immediately after triggering the reset. This signals other driver components to skip register accesses while the device is offline. A memory
