Details

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: TC, skip peer flow cleanup when LAG seq is unavailable mlx5_lag_get_dev_seq() will return error when the peer isn't in the LAG or when no device is marked as master. Result bad memory access and kernel crash[1]. Hence, skip the peer when lookup fails. Note: In case there are peer flows, they are cleaned before LAG cleared the master mark.
