## Summary A malformed packet can trigger memory corruption in the kernel leading to a system crash or potentially arbitrary code execution in the kernel. The CAN driver for the CTU CAN FD IP Core connected to the NuttX device via a PCI / PCI Express (PCIe) bus shows a lack of consideration for malformed data, assuming the CAN frames are always correct. Ensure `frame->fmt.rwcnt` is 21 or less before it is used in the `for` loop. A similar change was done in ctucanfd_sock_recv(). ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
