In the Linux kernel, the following vulnerability has been resolved: riscv: mm: add missing memcpy in kasan_init Hi Atish, It seems that the panic is due to the missing memcpy during kasan_init. Could you please check whether this patch is helpful? When doing kasan_populate, the new allocated base_pud/base_p4d should contain kasan_early_shadow_{pud, p4d}'s content. Add the missing memcpy to avoid page fault when read/write kasan shadow region. Tested on: - qemu with sv57 and CONFIG_KASAN on. - qemu with sv48 and CONFIG_KASAN on.
