"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libipw: fix key index receive bound checks\n\nlibipw_rx() reads skb->data[hdrlen + 3] to extract the WEP key index in\nboth the software-decrypt key selection path and the hardware-decrypted\nIV/ICV strip path. In both places the existing guard only checks\nskb->len >= hdrlen + 3, which proves bytes up to hdrlen + 2 but not the\nbyte at hdrlen + 3.\n\nRequire hdrlen + 4 bytes before reading that item in both paths. This is\na local source-boundary check only; it does not change the key index\nsemantics."
