In the Linux kernel, the following vulnerability has been resolved:
tracefs: Use generic inode RCU for synchronizing freeing
With structure layout randomization enabled for 'struct inode' we need to
avoid overlapping any of the RCU-used / initialized-only-once members,
e.g. i_lru or i_sb_list to not corrupt related list traversals when making
use of the rcu_head.
For an unlucky structure layout of 'struct inode' we may end up with the
following splat when running the ftrace selftests:
[] list_del corruption, ffff888103ee2cb0->next (tracefs_inode_cache+0x0/0x4e0 [slab object]) is NULL (prev is tracefs_inode_cache+0x78/0x4e0 [slab object])
