Detailed vulnerability description
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.
