An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-54051 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-54051/ (Markdown: https://insights.sbomify.com/CVE-2023-54051/index.md)","id":"CVE-2023-54051","markdown":"https://insights.sbomify.com/CVE-2023-54051/index.md","name":"CVE-2023-54051","record":{"aliases":["BELL-CVE-2023-54051","DEBIAN-CVE-2023-54051","GHSA-jqw4-r57w-p985","UBUNTU-CVE-2023-54051"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing check in the Linux kernel network stack allows remote attackers to cause a denial of service via crafted GSO packets.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: do not allow gso_size to be set to GSO_BY_FRAGS\n\nOne missing check in virtio_net_hdr_to_skb() allowed\nsyzbot to crash kernels again [1]\n\nDo not allow gso_size to be set to GSO_BY_FRAGS (0xffff),\nbecause this magic value is used by the kernel.\n\n[1]\ngeneral protection fault, probably for non-canonical address 0xdffffc000000000e: 0000 [#1] PREEMPT SMP KASAN\nKASAN: null-ptr-deref in range [0x0000000000000070-0x0000000000000077]\nCPU: 0 PID: 5039 Comm: syz-executor401 Not tainted 6.5.0-rc5-next-20230809-syzkaller #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/26/2023\nRIP: 0010:skb_segment+0x1a52/0x3ef0 net/core/skbuff.c:4500\nCode: 00 00 00 e9 ab eb ff ff e8 6b 96 5d f9 48 8b 84 24 00 01 00 00 48 8d 78 70 48 b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 \u003c0f\u003e b6 04 02 84 c0 74 08 3c 03 0f 8e ea 21 00 00 48 8b 84 24 00 01\nRSP: 0018:ffffc90003d3f1c8 EFLAGS: 00010202\nRAX: dffffc0000000000 RBX: 000000000001fffe RCX: 0000000000000000\nRDX: 000000000000000e RSI: ffffffff882a3115 RDI: 0000000000000070\nRBP: ffffc90003d3f378 R08: 0000000000000005 R09: 000000000000ffff\nR10: 000000000000ffff R11: 5ee4a93e456187d6 R12: 000000000001ffc6\nR13: dffffc0000000000 R14: 0000000000000008 R15: 000000000000ffff\nFS: 00005555563f2380(0000) GS:ffff8880b9800000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 0000000020020000 CR3: 000000001626d000 CR4: 00000000003506f0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n\u003cTASK\u003e\nudp6_ufo_fragment+0x9d2/0xd50 net/ipv6/udp_offload.c:109\nipv6_gso_segment+0x5c4/0x17b0 net/ipv6/ip6_offload.c:120\nskb_mac_gso_segment+0x292/0x610 net/core/gso.c:53\n__skb_gso_segment+0x339/0x710 net/core/gso.c:124\nskb_gso_segment include/net/gso.h:83 [inline]\nvalidate_xmit_skb+0x3a5/0xf10 net/core/dev.c:3625\n__dev_queue_xmit+0x8f0/0x3d60 net/core/dev.c:4329\ndev_queue_xmit include/linux/netdevice.h:3082 [inline]\npacket_xmit+0x257/0x380 net/packet/af_packet.c:276\npacket_snd net/packet/af_packet.c:3087 [inline]\npacket_sendmsg+0x24c7/0x5570 net/packet/af_packet.c:3119\nsock_sendmsg_nosec net/socket.c:727 [inline]\nsock_sendmsg+0xd9/0x180 net/socket.c:750\n____sys_sendmsg+0x6ac/0x940 net/socket.c:2496\n___sys_sendmsg+0x135/0x1d0 net/socket.c:2550\n__sys_sendmsg+0x117/0x1e0 net/socket.c:2579\ndo_syscall_x64 arch/x86/entry/common.c:50 [inline]\ndo_syscall_64+0x38/0xb0 arch/x86/entry/common.c:80\nentry_SYSCALL_64_after_hwframe+0x63/0xcd\nRIP: 0033:0x7ff27cdb34d9","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"net: do not allow gso_size to be set to GSO_BY_FRAGS","id":"CVE-2023-54051","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"wifi: mt76: mt7921: fix skb leak by txs missing in AMSDU","id":"CVE-2023-54052"},"packages":[],"prev":{"headline":"ubifs: Fix memleak when insert_old_idx() failed","id":"CVE-2023-54050"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing check in the Linux kernel network stack allows remote attackers to cause a denial of service via crafted GSO packets.","url":"https://insights.sbomify.com/CVE-2023-54051/"}
