  "summary": "staging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop\n\nThe IE parsing loop in OnAssocRsp() advances by (pIE->length + 2) each\niteration but only guards on i < pkt_len. When a malicious AP sends an\nAssocResponse whose last IE has only one byte remaining in the frame\n(the element_id byte lands at pkt_len-1), the loop reads pIE->length\nfrom pframe[pkt_len], which is one byte past the allocated receive buffer.\n\nAdditionally, even when the header bytes are in bounds, pIE->length\nitself can extend the data window beyond pkt_len, silently passing a\ntruncated IE to the handler functions.\n\nAdd two guards at the top of the loop body:\n  1. Break if fewer than sizeof(*pIE) bytes remain (can't read header).\n  2. Break if the IE's declared data extends past pkt_len.",
