What is CVE-2025-39751?

A buffer overflow vulnerability has been identified in the advanced Linux sound architecture (ALSA) component of the Linux kernel. The issue arises in the 'add_tuning_control' function, where the use of 'sprintf' can lead to an overflow if the length of the input strings exceeds 44 bytes. This flaw has been addressed by replacing 'sprintf' with 'snprintf', which restricts the length of the strings to mitigate the risk of overflow and improve overall security. It is recommended that users update to the patched version to safeguard against potential exploitation.
