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-2024-40907 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-40907/ (Markdown: https://insights.sbomify.com/CVE-2024-40907/index.md)","id":"CVE-2024-40907","markdown":"https://insights.sbomify.com/CVE-2024-40907/index.md","name":"CVE-2024-40907","record":{"aliases":["BELL-CVE-2024-40907","DEBIAN-CVE-2024-40907","GHSA-gv3v-qg2j-v72x","UBUNTU-CVE-2024-40907"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free bug in the ionic network driver causes a kernel panic when processing XDP_TX actions, leading to system denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nionic: fix kernel panic in XDP_TX action\n\nIn the XDP_TX path, ionic driver sends a packet to the TX path with rx\npage and corresponding dma address.\nAfter tx is done, ionic_tx_clean() frees that page.\nBut RX ring buffer isn't reset to NULL.\nSo, it uses a freed page, which causes kernel panic.\n\nBUG: unable to handle page fault for address: ffff8881576c110c\nPGD 773801067 P4D 773801067 PUD 87f086067 PMD 87efca067 PTE 800ffffea893e060\nOops: Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC KASAN NOPTI\nCPU: 1 PID: 25 Comm: ksoftirqd/1 Not tainted 6.9.0+ #11\nHardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021\nRIP: 0010:bpf_prog_f0b8caeac1068a55_balancer_ingress+0x3b/0x44f\nCode: 00 53 41 55 41 56 41 57 b8 01 00 00 00 48 8b 5f 08 4c 8b 77 00 4c 89 f7 48 83 c7 0e 48 39 d8\nRSP: 0018:ffff888104e6fa28 EFLAGS: 00010283\nRAX: 0000000000000002 RBX: ffff8881576c1140 RCX: 0000000000000002\nRDX: ffffffffc0051f64 RSI: ffffc90002d33048 RDI: ffff8881576c110e\nRBP: ffff888104e6fa88 R08: 0000000000000000 R09: ffffed1027a04a23\nR10: 0000000000000000 R11: 0000000000000000 R12: ffff8881b03a21a8\nR13: ffff8881589f800f R14: ffff8881576c1100 R15: 00000001576c1100\nFS: 0000000000000000(0000) GS:ffff88881ae00000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: ffff8881576c110c CR3: 0000000767a90000 CR4: 00000000007506f0\nPKRU: 55555554\nCall Trace:\n\u003cTASK\u003e\n?
