In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop
The IE parsing loop in OnAssocRsp() advances by (pIE->length + 2) each iteration but only guards on i < pkt len. When a malicious AP sends an AssocResponse whose last IE has only one byte remaining in the frame (the element id byte lands at pkt len-1), the loop reads pIE->length from pframe[pkt len], which is one byte past the allocated receive buffer.
Additionally, even when the header bytes are in bounds, pIE->length itself can extend the data window beyond pkt len, silently passing a truncated IE to the handler functions.
Add two guards at the top of the loop body:
  1. Break if fewer than sizeof(*pIE) bytes remain (can't read header).
  2. Break if the IE's declared data extends past pkt len.
