kernel: Linux kernel: Denial of Service in mlx5e due to incorrect encap attribute handling

A flaw was found in the mlx5e Traffic Control TC encapsulation logic in the net/mlx5e driver of the Linux kernel. The code responsible for invalidating encapsulation actions did not use the proper helper function to retrieve the correct encapsulation attribute, instead assuming the default...

kernel: net/mlx5e: TC, Fix using eswitch mapping in nic mode

A flaw was found in the Linux kernel net/mlx5e Ethernet driver’s traffic control handling code. Under certain configurations when operating in NIC mode, the driver erroneously uses the eswitch object mapping pool, which is not initialized in that mode. This can lead to an invalid mapping referenc...

kernel: net/mlx5e: Fix cleanup null-ptr deref on encap lock

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix cleanup null-ptr deref on encap lock During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next duri...
