In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Take RTNL lock when needed before calling xdp_set_features() Hold RTNL lock when calling xdp_set_features() with a registered netdev, as the call triggers the netdev notifiers. This could happen when switching from uplink rep to nic profile for example. This resolves the following call trace: RTNL: assertion failed at net/core/dev.c (1953) WARNING: CPU: 6 PID: 112670 at net/core/dev.c:1953 call_netdevice_notifiers_info+0x7c/0x80 Modules linked in: sch_mqprio sch_mqprio_lib act_tunnel_key act_mirred act_skbedit cls_m
