Subject: [PATCH 22/90] fdt: Fix bounds check in devfdt_get_addr_index
|
|
|
|
reg must contain enough cells for the entire next address/size pair
|
|
after skipping `index` pairs. The previous code allows an out-of-bounds
|
|
read when na + ns > 1.
|
|
|
|

Fixes: 69b41388ba45 ("dm: core: Add a new api to get indexed device address")
