  "description": "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}\u0027s 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.",
