https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=342ccffd9f77fc29fe1c05fd145e4d842bd2feaa

which was committed on 2025-11-28, so the last time I got the issue
(only a few days later), the kernel (6.*) did not have the fix.

BTW, this is CVE-2025-71305:

Yes, the machine in question is running unstable (though I sometimes
uses an older kernel due to another bug, which is not fixed yet).

So I suppose that this bug could now be closed.
