About this tag
The nfc spi tag on WindowsForum.com covers discussions about the Linux kernel's NFC (Near-Field Communication) stack, specifically the SPI transport path for NCI devices. Content includes a thread detailing a NULL-pointer vulnerability (CVE-2023-46343) in the NFC NCI SPI code, which was fixed in Linux 6.5.9. The bug could cause a local denial-of-service by crashing kernels handling NFC traffic. The tag focuses on kernel-level NFC SPI issues, security patches, and related technical fixes. While the tag is Linux-centric, it may be relevant to Windows users running Linux subsystems or virtual machines that interact with NFC hardware via SPI.
