From 9eba69df1cd37c564e414165fd6e6314543427d9 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Mon, 7 Dec 2015 00:10:15 -0500 Subject: udev: fix NULL deref when executing rules We quite obviously check whether event->dev_db is nonnull, and right after that call a function which asserts the same. Move the call under the same if. https://bugzilla.redhat.com/show_bug.cgi?id=1283971 --- src/udev/udev-event.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/udev') diff --git a/src/udev/udev-event.c b/src/udev/udev-event.c index 2ef8bfe59e..8d601c9c2c 100644 --- a/src/udev/udev-event.c +++ b/src/udev/udev-event.c @@ -848,11 +848,11 @@ void udev_event_execute_rules(struct udev_event *event, /* disable watch during event processing */ if (major(udev_device_get_devnum(dev)) != 0) udev_watch_end(event->udev, event->dev_db); - } - if (major(udev_device_get_devnum(dev)) == 0 && - streq(udev_device_get_action(dev), "move")) - udev_device_copy_properties(dev, event->dev_db); + if (major(udev_device_get_devnum(dev)) == 0 && + streq(udev_device_get_action(dev), "move")) + udev_device_copy_properties(dev, event->dev_db); + } udev_rules_apply_to_event(rules, event, timeout_usec, timeout_warn_usec, -- cgit v1.2.3
