Linux Linux, linux kernel 취약점
In the Linux kernel, the following vulnerability has been resolved: sctp: fix uninit-value in __sctp_rcv_asconf_lookup() __sctp_rcv_asconf_lookup() in net/sctp/input.c only checks that the ASCONF chunk can hold the ADDIP header and a parameter header, then calls af->from_addr_param(), which reads the full address (16 bytes for IPv6) trusting the parameter's declared length.
