[ { "category": "description", "text": "In the Linux kernel, the following vulnerability has been resolved:\n\nrtase: Workaround for TX hang caused by hardware packet parsing\n\nThe hardware performs packet parsing before packet transmission.\nParsing incomplete IPv4, IPv6, TCP, or UDP headers may trigger a TX\nhang because the hardware parser expects additional protocol header\ndata that is not present in the packet.\n\nThe hardware performs additional PTP parsing on UDP packets identified\nby destination ports 319/320 at the expected UDP destination port\noffset.\n\nIf such a packet has transport data smaller than RTASE_MIN_PAD_LEN,\nthe hardware parser expects additional packet data and may trigger a\nTX hang.\n\nTo avoid these hardware issues, the driver applies the following\nworkarounds.\n\nDrop malformed packets that may trigger this hardware issue before\ntransmission.\n\nFor IPv4 non-initial fragments, the hardware does not check the\nfragment offset before parsing the expected transport header location.\nAs a result, these packets are still subject to transport header\nparsing even though they do not contain a transport header. If the\ntransport data is shorter than the minimum transport header required\nby the hardware parser, pad the transport data to the minimum\ntransport header length required by the hardware parser. Packets that\nalso match the hardware PTP parsing conditions continue to follow the\ncorresponding workaround.\n\nFor IPv6 fragmented packets, neither of the above hardware issues\noccurs because the hardware only continues packet parsing when the\nIPv6 Base Header Next Header field directly indicates UDP. Packets\ncarrying a Fragment Header do not continue through the subsequent\npacket parsing stages.\n\nFor packets identified for hardware PTP parsing, pad the transport\ndata so it reaches RTASE_MIN_PAD_LEN before transmission.", "title": "Vulnerability description" }, { "category": "other", "text": "TuxCare has assessed that this vulnerability does not impact any currently supported TuxCare products.
