[PATCH net-next] nfc: pn533: prevent potential memory corruption

2021-04-02 Thread Dan Carpenter
If the "type_a->nfcid_len" is too large then it would lead to memory corruption in pn533_target_found_type_a() when we do: memcpy(nfc_tgt->nfcid1, tgt_type_a->nfcid_data, nfc_tgt->nfcid1_len); Fixes: c3b1e1e8a76f ("NFC: Export NFCID1 from pn533") Signed-off-by: Dan Carpenter --- drivers
