"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix heap buffer overflow in rtw_cfg80211_set_wpa_ie()\n\nsupplicant_ie is a 256-byte array in struct security_priv. The WPA and\nWPA2 IE copy paths use:\n\n memcpy(padapter->securitypriv.supplicant_ie, &pwpa[0], wpa_ielen + 2);\n\nwhere wpa_ielen is the raw IE length field (u8, 0-255). When a local user\nsupplies a connect request via nl80211 with a crafted WPA IE of length 255,\nwpa_ielen + 2 equals 257, overflowing the 256-byte buffer by one byte into\nthe adjacent last_mic_err_time field.\n\nrtw_parse_wpa_ie() does not prevent this: its length consistency check\ncompares *(wpa_ie+1) against (u8)(wpa_ie_len-2), which is (u8)(255) == 255\nwhen wpa_ie_len = 257, so the check passes silently.\n\nAdd explicit bounds checks for both the WPA and WPA2 paths before the\nmemcpy, rejecting any IE whose total size (wpa_ielen + 2) exceeds the\nsupplicant_ie buffer."
