Component: Not specified by the source
File: net/sctp/bind_addr.c, net/sctp/sm_make_chunk.c

Attack conditions (Source advisory, CVSS 3.1): Network (remote) · No privileges required · No user interaction required

What an attacker can do

The source says when cookie authentication is disabled, an attacker can supply an oversized raw_addr_list_len and cause sctp_raw_to_bind_addrs() to read beyond the end of the cookie. Source advisory’s CVSS 3.1 assessment (base score 9.1/10) rates confidentiality and availability impact as high; integrity impact as none.
