In the Linux kernel, the following vulnerability has been resolved:
ASoC: codec: sma1307: Fix memory corruption in sma1307_setting_loaded()
The sma1307->set.header_size is how many integers are in the header
(there are 8 of them) but instead of allocating space of 8 integers
we allocate 8 bytes. This leads to memory corruption when we copy data
it on the next line:
memcpy(sma1307->set.header, data,
sma1307->set.header_size * sizeof(int));
Also since we're immediately copying over the memory in ->set.header,
there is no need to zero it in the allocator. Use devm_kmalloc_array()
to allocate the memory instead.
