Описание
Оригинално описание
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix OOB reads in IE loops in issue_assocreq() and join_cmd_hdl() Two IE parsing loops are missing the header bounds checks before they dereference pIE->length: - issue_assocreq() walks pmlmeinfo->network.ies to build the association request. If the stored IE data ends with only an element_id byte and no length byte, pIE->length is read one byte past the end of the buffer. - join_cmd_hdl() walks pnetwork->ies during station join and has the same problem under the same conditions. Both buffers are filled from AP beacon and probe-response frames, so a malicious AP that sends a truncated final IE can trigger the issue. Apply the two-guard pattern established in update_beacon_info(): 1. Break if fewer than sizeof(*pIE) bytes remain. 2. Break if the IE's declared data extends past the buffer end.
