@Jean-Baptiste, I think I've found the offending bug and upstream commit 3d861f661006606bf159fd6bd973e83dbf21d0f9 "net: fix secpath kmemleak" fixes a reference counting issue that stops lo from becoming free.
I've build some test kernels, perhaps you could try the appropriate one and let me know if it resolves the bug for you.
