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