This looks like a duplicate of #16501, fixed by #16539. We'll pull this fix in to the 2.2.7 release when we enable support by default for the 6.11 kernel.
For posterity, defect is present in OpenSUSE Tumbleweed, Kernel 6.11.3, ZFS 2.2.6-1
Thanks for the updates. No need to keep posting them from here, it's not a defect, rather a false positive in the kernel memory checker. Already "fixed" on master, and that fix will be included in future releases that officially support 6.11 (2.2.7, 2.3.0) (per @behlendorf's comment above). Thanks!
it's not a defect, rather a false positive in the kernel memory checker
ok, that's reassuring :)
FYI: still happens with pretty recent master (~ December 15th)

This warning was fixed in 2.2.7 and 2.3.0 (#16539) for the instances around zfs_log, lr+1 and similar.
@zachariasmaladroit, your case is the same shape of problem, not covered by the existing fix. It is still a false-positive, but definitely one we should silence. If you're able, could you please open a new issue; I'm afraid this one got lost at the bottom of a set of very similar-looking stack traces. Thanks!
