Linux kernel is vulnerable to denial of service (DOS) attacks. The vulnerability exists in the ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel. Malicious IP options present would cause the ipv4_pktinfo_prepare() function to drop/free the dst. Attackers could cause a denial of service (system crash) condition via a crafted system call or IPv4 traffic with invalid IP options.
