I just checked and I'm shocked: ``` $ grep KASAN /boot/config-6.1.18-100.fc36.x86_64+debug CONFIG_HAVE_ARCH_KASAN=3Dy CONFIG_HAVE_ARCH_KASAN_VMALLOC=3Dy CONFIG_CC_HAS_KASAN_GENERIC=3Dy # CONFIG_KASAN is not set ``` So we really need a KASAN-enabled kernel to reproduce the KASAN error repor= t, obviously :) --=20 You are receiving this mail because: You are the assignee for the bug.=
