This signature detects attempts to exploit a known vulnerability in the SCTP networking module of the Linux kernel. A successful exploitation could result in denial of service conditions.
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.
