Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
staging: rtl8723bs: fix OOB read in OnAssocRsp() IE loop<br />
<br />
The IE parsing loop in OnAssocRsp() advances by (pIE->length + 2) each<br />
iteration but only guards on i length<br />
from pframe[pkt_len], which is one byte past the allocated receive buffer.<br />
<br />
Additionally, even when the header bytes are in bounds, pIE->length<br />
itself can extend the data window beyond pkt_len, silently passing a<br />
truncated IE to the handler functions.<br />
<br />
Add two guards at the top of the loop body:<br />
1. Break if fewer than sizeof(*pIE) bytes remain (can&#39;t read header).<br />
2. Break if the IE&#39;s declared data extends past pkt_len.
Impacto
