--- Comment #4 from agentzh <agentzh at gmail dot com> ---
Just for a side note: Fedora's kernel-debug kernels do not enable KASAN at all.
I just checked and I'm shocked:

```
$ grep KASAN /boot/config-6.1.18-100.fc36.x86_64+debug
CONFIG_HAVE_ARCH_KASAN=y
CONFIG_HAVE_ARCH_KASAN_VMALLOC=y
CONFIG_CC_HAS_KASAN_GENERIC=y
# CONFIG_KASAN is not set
```

So we really need a KASAN-enabled kernel to reproduce the KASAN error report,
obviously :)
