CVE-2016-9555

CRITICAL9.8

The sctp_sf_ootb function in net/sctp/sm_statefuns

Published Nov 28, 2016

Modified 1 years ago

No fix available

Details

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.
