resolved:\n\nsctp: fix uninit-value in __sctp_rcv_asconf_lookup()\n\n__sctp_rcv_asconf_lookup() in net/sctp/input.c only checks that the ASCONF\nchunk can hold the ADDIP header and a parameter header, then calls\naf->from_addr_param(), which reads the full address (16 bytes for IPv6)\ntrusting the parameter's declared length.\n\nAn unauthenticated peer can send a truncated trailing ASCONF chunk that\ndeclares an IPv6 address parameter but stops after the 4-byte parameter\nheader; reached from the no-association lookup path, from_addr_param() then\nreads uninitialized bytes past the parameter.\n\nImpact: an unauthenticated SCTP peer makes the receive path read up to 16\nbytes of uninitialized memory past a truncated ASCONF address parameter.\n\nThe sibling __sctp_rcv_init_lookup() bounds parameters with\nsctp_walk_params(); this path open-codes the fetch and omits the bound.\nVerify the whole address parameter lies within the chunk before\nfrom_addr_param() reads it, the same class of fix as commit 51e5ad549c43\n(\"net: sctp: fix KMSAN uninit-value in sctp_inq_pop\")."}], "lastModified": "2026-07-02T20:46:44.463",
