Description
A flaw was found in the Linux kernel's Near Field Communication (NFC) pn533 driver. This vulnerability arises from an issue in how the driver manages receive buffers. When processing incoming data, the driver may attempt to write to a non-existent buffer if a new one fails to allocate. This can lead to a system crash, resulting in a Denial of Service (DoS).
