In the Linux kernel, the following vulnerability has been resolved:
nfc: digital: clamp SENSF RES length to the destination buffer
digital in recv sensf res() memcpy()s resp->len bytes from a remote NFC-F device response into the NFC SENSF RES MAXSIZE-byte target.sensf res field without an upper-bound check. A nearby malicious NFC-F device can send an oversized SENSF RES response to overflow the stack-local struct nfc target.
Clamp resp->len to NFC SENSF RES MAXSIZE before the copy.
