In the Linux kernel, the following vulnerability has been resolved:
riscv: Sync efi page table's kernel mappings before switching
The EFI page table is initially created as a copy of the kernel page table.
With VMAP_STACK enabled, kernel stacks are allocated in the vmalloc area:
if the stack is allocated in a new PGD (one that was not present at the
moment of the efi page table creation or not synced in a previous vmalloc
fault), the kernel will take a trap when switching to the efi page table
when the vmalloc kernel stack is accessed, resulting in a kernel panic.
Fix that by updating the efi kernel mappings before switching to the efi
page table.
