CVE-2026-80803

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A stack-based buffer overflow exists in the digital in recv sensf res() function. The issue occurs when the function uses memcpy() to copy resp->len bytes from a remote NFC-F device response into the target.sensf res field of the nfc target struct without performing an upper-bound check. A malicious nearby NFC-F device could send an oversized SENSF RES response to trigger this overflow.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
