Description
The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.
A design flaw was found in the file extended attribute handling of the Linux kernel's handling of cached attributes. Too many entries in the cache cause a soft lockup while attempting to iterate the cache and access relevant locks.
