Linux CVE-2025-39935

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.
