This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move.

Description
A security flaw was found in the Linux kernel that an attempt to move page mapped by AIO ring buffer to the other node triggers NULL pointer dereference at trace_writeback_dirty_page(), because aio_fs_backing_dev_info.dev is 0.
