Detail

In the Linux kernel, the following vulnerability has been resolved:

block: don't delete queue kobject before its children

kobjects aren't supposed to be deleted before their child kobjects are deleted. Apparently this is usually benign; however, a WARN will be triggered if one of the child kobjects has a named attribute group:

sysfs group 'modes' not found for kobject 'crypto'
WARNING: CPU: 0 PID: 1 at fs/sysfs/group.c:278 sysfs_remove_group+0x72/0x80
...
Call Trace:

Fix this by moving the kobject_del() and the corresponding kobject_uevent() to the correct place.
