CVE-2026-64444
Beschrijving NL
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 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.
