+Subject: [PATCH] vsnprintf_s: Increase Buffer Size by 1
+
+It is a buffer overflow warning that GCC 15.2 is catching.
+The issue is that it's trying to write to `buf[len++]` when len could
+potentially be 31, which would write to buf[31] in a buffer of size 32
+(valid indices 0-31), but the len++ post-increment means it could
+theoretically write beyond the buffer bounds.
+
+Fixes
