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():

  • Break if fewer than sizeof(*pIE) bytes remain.
  • Break if the IE's declared data extends past the buffer end.
