CVE-2026-80803
N/A
N/A
Summary
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.
Found by 0sec automated security-research tooling (https://0sec.ai).
