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-2024-26626 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-2024-26626/ (Markdown: https://insights.sbomify.com/CVE-2024-26626/index.md)","id":"CVE-2024-26626","markdown":"https://insights.sbomify.com/CVE-2024-26626/index.md","name":"CVE-2024-26626","record":{"aliases":["BELL-CVE-2024-26626","DEBIAN-CVE-2024-26626","GHSA-6p64-gpr7-7mjm","UBUNTU-CVE-2024-26626"],"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 null pointer dereference in the Linux kernel's IP multicast routing code allows attackers to cause a system crash via crafted multicast packets.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipmr: fix kernel panic when forwarding mcast packets\n\nThe stacktrace was:\n[   86.305548] BUG: kernel NULL pointer dereference, address: 0000000000000092\n[   86.306815] #PF: supervisor read access in kernel mode\n[   86.307717] #PF: error_code(0x0000) - not-present page\n[   86.308624] PGD 0 P4D 0\n[   86.309091] Oops: 0000 [#1] PREEMPT SMP NOPTI\n[   86.309883] CPU: 2 PID: 3139 Comm: pimd Tainted: G     U             6.8.0-6wind-knet #1\n[   86.311027] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.11.1-0-g0551a4be2c-prebuilt.qemu-project.org 04/01/2014\n[   86.312728] RIP: 0010:ip_mr_forward (/build/work/knet/net/ipv4/ipmr.c:1985)\n[ 86.313399] Code: f9 1f 0f 87 85 03 00 00 48 8d 04 5b 48 8d 04 83 49 8d 44 c5 00 48 8b 40 70 48 39 c2 0f 84 d9 00 00 00 49 8b 46 58 48 83 e0 fe \u003c80\u003e b8 92 00 00 00 00 0f 84 55 ff ff ff 49 83 47 38 01 45 85 e4 0f\n[   86.316565] RSP: 0018:ffffad21c0583ae0 EFLAGS: 00010246\n[   86.317497] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000000\n[   86.318596] RDX: ffff9559cb46c000 RSI: 0000000000000000 RDI: 0000000000000000\n[   86.319627] RBP: ffffad21c0583b30 R08: 0000000000000000 R09: 0000000000000000\n[   86.320650] R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000001\n[   86.321672] R13: ffff9559c093a000 R14: ffff9559cc00b800 R15: ffff9559c09c1d80\n[   86.322873] FS:  00007f85db661980(0000) GS:ffff955a79d00000(0000) knlGS:0000000000000000\n[   86.324291] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[   86.325314] CR2: 0000000000000092 CR3: 000000002f13a000 CR4: 0000000000350ef0\n[   86.326589] Call Trace:\n[   86.327036]  \u003cTASK\u003e\n[   86.327434] ?
