See the security database (you can also search it by CVE number, so you do not need to open posts here ):

It is obviously in progress but fixed for a bunch of kernel/OS constellations already, looking at the list I’d expect linux-hwe for 6.8 to be the next to be fixed (once all porting and testing of the fixes has finished) after which the pc-kernel snap should automatically re-build …
