Description

1) Out-of-bounds read (CVE-ID: CVE-2017-7558)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local attacker to obtain potentially sensitive information.
The weakness exists due to put-of-bounds read in the inet_diag_msg_sctpaddrs_fill(), inet_diag_msg_sctpladdrs_fill(), and sctp_get_sctp_info() functions in 'net/sctp/sctp_diag.c'. A local attacker can gain access to important data in portions of slab memory on the target system.
