Damaged Brick/mortar around external pipe - water ingress

[DMR80]

Hi,

I'm hoping someone may be able to offer advice. I have a combi boiler in the bedroom. A pipe from the combi feeds down into the living room and out the external wall. After heavy rain today a small amount of water is getting into the living from where pipes feeds outside. After inspection outside part of the brick next to the pipe is completely cracked - I could pull it out with my hand, the mortar has also crumbled.

Could I fix this myself by simply cementing around the pipe? Any advice welcome. Pics attached. Thanks

Yes, remove all loose material and repack the void with a spot of decent mortar.
