Description OSIDB Bzimport 2025-06-18 12:07:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: avs: Fix potential buffer overflow by snprintf()

snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in a buffer
overflow (although it's unrealistic).

This patch replaces it with a safer version, scnprintf() for papering
over such a potential issue.
