In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: Fix buffer overflow in config retrieval The scarlett2_usb_get_config() function has a logic error in the endianness conversion code that can cause buffer overflows when count > 1. The code checks `if (size == 2)` where `size` is the total buffer size in bytes, then loops `count` times treating each element as u16 (2 bytes). This causes the loop to access `count * 2` bytes when the buffer only has `size` bytes allocated. Fix by checking the element size (config_item->size) instead of the total buffer size. This ensures the endianness conversion matches the actual element type.
