02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: net/core: Fix ETH_P_1588 flow dissector When a PTP ethernet raw frame with a size of more than 256 bytes followed by a 0xff pattern is sent to __skb_flow_dissect, nhoff value calculation is wrong. For example: hdr->message_length takes the wrong value (0xffff) and it does not replicate real header length. In this case, 'nhoff' value was overridden and the PTP header was badly dissected. This leads to a kernel crash. net/core: flow_dissector... • https://git.kernel.org/stable/c/4f1cc51f34886d645cd3e8fc2915cc9b7a55c3b6 • CWE-131: Incorrect Calculation of Buffer Size •
