I wouldn't change the CR. The undead you're talking about are just too fragile to start with, so this ability brings them up to par. I would warn the players that these monsters will be harder to kill than before, though.
LA doesn't matter unless you have vampire and lich PCs, which I'd guess isn't the case.
I agree with hong that the undead are too fragile to start with, but you as the GM still may want to change the CR if your group was having trouble with the old fragile versions. Myself, I've already been handing this out to certain undead in my games, and it makes a
huge difference--take a look at Xan and Kari, two level 40 Shadow Liches (Xan is the Shadow Lich in my game's main world, Kari comes from an alternate shadow dimension--both are basically
the most powerful undead entities around, although the group managed to thwart Xan once by desroying his phylactery). Note how Kari is
much harder to kill and Xan is basically a joke when he isn't possessing somebody's body
