| Description: | The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel before 4.8.8 lacks chunk-length checking for the first chunk, which allows remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data. Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation of incoming data. A remote attacker could use this to cause a denial of service (system crash).
