error: implicit declaration of function ‘strlcpy’; did you mean ‘strscpy’? [-Werror=implicit-function-declaration]

Hello VirtualBox Team,

I notice this today when using CDROM file - VBox_GAs_7.0.14 to install drivers in Guest VM Linux. But i notice error when trying to install additional guest drivers.

Snip errors:

/tmp/vbox.0/VBoxGuest-linux.c: In function ‘vgdrvLinuxParamLogGrpSet’:
/tmp/vbox.0/VBoxGuest-linux.c:1364:9: error: implicit declaration of function ‘strlcpy’; did you mean ‘strscpy’? [-Werror=implicit-function-declaration]
 1364 |         strlcpy(&g_szLogGrp[0], pszValue, sizeof(g_szLogGrp));
      |         ^~~~~~~
      |         strscpy

Host OS: OpenSUSE Tw, virtuabox version: virtualbox-7.0.14-7.1 Guest VM OS: Debian 13 Trixie Testing, 6.8.5-lowlatency kernel version

Hey, I guess I am facing a similar issue after installing the latest kernel on Proxmox Backup Server; Debian 12.5; kernel 6.8.4-2-pve; after running

root@pbsbn:/mnt/cdrom# sudo sh ./VBoxLinuxAdditions.run

cat /var/log/vboxadd-setup.log
