Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> staging: rtl8723bs: fix OOB reads in is_ap_in_tkip() IE loop<br /> <br /> The loop in is_ap_in_tkip() iterates over IEs without verifying that<br /> enough bytes remain before dereferencing the IE header or its payload:<br /> <br /> - pIE-&gt;element_id and pIE-&gt;length are read without checking that<br /> i + sizeof(*pIE) data + 12,<br /> which requires pIE-&gt;length &gt;= 16. For WLAN_EID_RSN it compares<br /> pIE-&gt;data + 8, requiring pIE-&gt;length &gt;= 12. Neither requirement<br /> is checked.<br /> <br /> Add the missing IE header and payload bounds checks and guard each<br /> data access with an explicit pIE-&gt;length minimum, matching the<br /> pattern established in update_beacon_info().
