CVE-2026-64444

High 8.1

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.
