- Summary
- ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ipv4: iptunnel: Fix suspicious RCU usage warning in iptunnelinitflow()
There are code paths from which the function is called without holding the RCU read lock, resulting in a suspicious RCU usage warning [1].
Fix by using l3mdevmasterupperifindexbyindex() which will acquire the RCU read lock before calling l3mdevmasterupperifindexbyindex_rcu().
[1] WARNING: suspicious RCU usage
6.12.0-rc3-custom-gac8f72681cf2 #141 Not tainted
