kernel: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

A flaw was found in the Linux kernel. A local attacker can exploit an out-of-bounds write vulnerability when the kernel recomputes an IPv6 Source Routing Header SRH. This issue occurs because insufficient headroom is reserved during the recompression process, leading to memory corruption...
