Description
In the Linux kernel, the following vulnerability has been resolved:
pstore: ram_core: fix incorrect success return when vmap() fails
In persistent_ram_vmap(), vmap() may return NULL on failure.
If offset is non-zero, adding offset_in_page(start) causes the function
to return a non-NULL pointer even though the mapping failed.
persistent_ram_buffer_map() therefore incorrectly returns success.
Subsequent access to prz->buffer may dereference an invalid address
and cause crashes.
Add proper NULL checking for vmap() failures.
