CVE-2026-12630
In Zephyr's 6LoWPAN stack, get_ihpc_inlined_size() in subsys/net/ip/6lo.c indexes a 13-entry table with a 4-bit value (0-15) from the incoming IPHC dispatch word. Reserved indices 13-15 are unchecked, causing an out-of-bounds read that drives further buffer dereference and size_t underflow before...
