"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware_loader: Fix recursive lock in device_cache_fw_images()\n\nA recursive locking deadlock can occur in the firmware loader's power\nmanagement notification handler.\n\nDuring system suspend or hibernation preparation, fw_pm_notify() calls\ndevice_cache_fw_images(). This function acquires fw_lock to set the\nfirmware cache state to FW_LOADER_START_CACHE and then iterates over all\ndevices using dpm_for_each_dev() while still holding the lock.\n\nFor each device, dev_cache_fw_image() schedules asynchronous work to cache\nthe firmware. If memory allocation for the async work entry fails (e.g., in\nout-of-memory conditions), async_schedule_node_domain() falls back to\nexecuting the work function synchronously in the current thread.\n\nThe synchronous execution path (__async_dev_cache_fw_image() ->\ncache_firmware() -> request_firmware() -> assign_fw()) attempts to acquire\nfw_lock again. Since the current thread already holds fw_lock, this results\nin a recursive locking deadlock.\n\nFix this by releasing fw_lock immediately after updating the cache state\nand before calling dpm_for_each_dev(). The lock is only needed to protect\nthe state update. Concurrent firmware requests will correctly see the\nFW_LOADER_START_CACHE state and use the piggyback mechanism, which is\nindependently protected by its own fwc->name_lock."
