Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net: fix possible store tearing in neigh_periodic_work()
While looking at a related syzbot report involving neigh_periodic_work(),
I found that I forgot to add an annotation when deleting an
RCU protected item from a list.
Readers use rcu_deference(*np), we need to use either
rcu_assign_pointer() or WRITE_ONCE() on writer side
to prevent store tearing.
I use rcu_assign_pointer() to have lockdep support,
this was the choice made in neigh_flush_dev().
A flaw was found in the Linux kernel that allows for potential store tearing within the neigh_periodic_work() function, meaning a write operation on a value is not protected properly and could result in inconsistencies if another process or thread reads from that value before the operation is complete.
