Random stuff > CVE-2022-0324 > Buffer Overflow in dhcp6relay of SONiC

Vuln: CVE-2022-0324 breaks the invariant that SONiC’s dhcp6relay must validate DHCPv6 option/payload lengths so it never copies more bytes than the destination buffer can hold.​The invariant is violated when a remote attacker sends a crafted DHCPv6 packet that reaches a memcpy with an unchecked length, causing an out-of-bounds write (buffer overflow).
