This bug should be fixed in Linux kernel 6.16; see:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fe78e02600f83d81e55f6fc352d82c4f264a2901
For what it's worth, Coreutils decided not to work around the bug,
and instead to suggest updating to a fixed kernel or to a future
version of libattr with at least the following patches:
