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