"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware_loader: fix device reference leak in firmware_upload_register()\n\nfirmware_upload_register()\n -> fw_create_instance()\n -> device_initialize()\n\nAfter fw_create_instance() succeeds, the lifetime of the embedded struct\ndevice is expected to be managed through the device core reference\ncounting, since fw_create_instance() has already called\ndevice_initialize().\n\nIn firmware_upload_register(), if alloc_lookup_fw_priv() fails after\nfw_create_instance() succeeds, the code reaches free_fw_sysfs and frees\nfw_sysfs directly instead of releasing the device reference with\nput_device(). This may leave the reference count of the embedded struct\ndevice unbalanced, resulting in a refcount leak.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review. Fix this by using put_device(fw_dev) in the\nfailure path and letting fw_dev_release() handle the final cleanup,\ninstead of freeing the instance directly from the error path."
