CVE-2021-47515

CVE-2021-47515 affects Linux kernel segmentation with IPv6 SRH encapsulation. When an IPv4 packet is received, the kernel assigns the receiving interface index to IPCB(iif). If that packet is later encapsulated in an outer IPv6+SRH header, seg6_do_srh_encap clears the IPv6 socket state (IP6CB) an...
