Subject: Re: KASAN: use-after-free Read in tc_chain_fill_node
This bug is marked as fixed by commit:
net: core: netlink: add helper refcount dec and lock function
net: sched: add helper function to take reference to Qdisc
net: sched: extend Qdisc with rcu
net: sched: rename qdisc_destroy() to qdisc_put()
net: sched: use Qdisc rcu API instead of relying on rtnl lock
But I can't find it in the tested trees[1] for more than 90 days.
Is it a correct commit? Please update it by replying:
#syz fix: exact-commit-title
Until then the bug is still considered open and new crashes with
the same signature are ignored.
