A vulnerability in the Linux kernel's DHCP option construction was resolved. The function ic_dhcp_init_options() appends DHCP options including hostname, vendor-class, and client-ID into a fixed-size buffer without proper bounds checking for hostname and vendor-class options. This can cause a buffer overflow when large option sizes are used, potentially leading to kernel panic during boot if CONFIG_FORTIFY_SOURCE and panic_on_warn=1 are enabled. The fix routes options through a helper that ensures size limits are respected, preventing buffer overruns.
