Debian Trixie is on 6.12. I would expect many Debian users to still be on Bookworm though, which is reported as “6.1 series”. Not sure if those would be affected. Most other distros will be on newer kernels than Debian.
Whichever kernel debian bookworm has, the patch for this has most likely been applied to it. The larger risk is to organizations running ancient versions of RHEL or something that never get updated, e.g. because some hardware they need uses a shitty proprietary driver that supports only very specific kernel versions.

I don’t have any machines still running Bookworm so I can’t check for myself.
Edit: I am a ding dong home user and don’t even use Linux for work (unfortunately). No idea how this affects entities larger than individuals like me
