What is CVE-2025-38629?

The ALSA subsystem of the Linux kernel has a vulnerability in the USB Scarlett2 driver that allows for potential NULL dereference errors. This issue arises in the function scarlett2_input_select_ctl_info(), where proper checks for NULL values are absent after allocating string arrays through kasprintf(). This oversight can lead to system instability or crashes if the function attempts to access a NULL pointer. Fixing this issue involves adding necessary NULL checks to ensure robust handling of memory allocations.
