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->element_id and pIE->length are read without checking that<br />
i + sizeof(*pIE) data + 12,<br />
which requires pIE->length >= 16. For WLAN_EID_RSN it compares<br />
pIE->data + 8, requiring pIE->length >= 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->length minimum, matching the<br />
pattern established in update_beacon_info().
