CVE-2023-52580

CVE-2023-52580 affects the Linux kernel net/core ETH_P_1588 flow dissector. When a PTP Ethernet raw frame larger than 256 bytes is followed by 0xff, the nhoff calculation uses hdr->message_length (0xffff) and may override nhoff, causing incorrect header length and a kernel crash. The disclosed...
