A flaw was found in the Linux kernel's PN533 NFC (Near Field Communication) driver. An attacker capable of connecting a malicious or malfunctioning USB device can supply a crafted response frame with an arbitrary data length value. Because the driver fails to validate this length against maximum frame boundaries before indexing the buffer, an out-of-bounds read occurs, potentially causing a Denial of Service (DoS) via system crash or disclosing sensitive kernel memory.
