A number of us are seeing a reproducible kernel memory leak on RPi.

There is a bug https://bugzilla.redhat.com/show_bug.cgi?id=2279327

Kernel 6.5.6 does not have a leak, but current kernels do.

Can you specify what you mean by "current kernels", I believe there is a aarch64 memory leak fix in 6.8.9, which is currently in testing. There's more info in the following bug:

https://bugzilla.redhat.com/show_bug.cgi?id=2275290

Sorry should have provided a version 6.8.8 is what I have.

I'll install the 6.8.9 kernel and test.

Anyone know if this is being looked at?
