It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-37867 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-37867/ (Markdown: https://insights.sbomify.com/CVE-2025-37867/index.md)","id":"CVE-2025-37867","markdown":"https://insights.sbomify.com/CVE-2025-37867/index.md","name":"CVE-2025-37867","record":{"aliases":["BELL-CVE-2025-37867","DEBIAN-CVE-2025-37867","GHSA-5m63-6f39-c6xq","ROOT-OS-DEBIAN-12-CVE-2025-37867","ROOT-OS-UBUNTU-2204-CVE-2025-37867","ROOT-OS-UBUNTU-2404-CVE-2025-37867","UBUNTU-CVE-2025-37867"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel warning via RDMA operations, potentially causing system instability or denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/core: Silence oversized kvmalloc() warning\n\nsyzkaller triggered an oversized kvmalloc() warning.\nSilence it by adding __GFP_NOWARN.\n\nsyzkaller log:\n WARNING: CPU: 7 PID: 518 at mm/util.c:665 __kvmalloc_node_noprof+0x175/0x180\n CPU: 7 UID: 0 PID: 518 Comm: c_repro Not tainted 6.11.0-rc6+ #6\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\n RIP: 0010:__kvmalloc_node_noprof+0x175/0x180\n RSP: 0018:ffffc90001e67c10 EFLAGS: 00010246\n RAX: 0000000000000100 RBX: 0000000000000400 RCX: ffffffff8149d46b\n RDX: 0000000000000000 RSI: ffff8881030fae80 RDI: 0000000000000002\n RBP: 000000712c800000 R08: 0000000000000100 R09: 0000000000000000\n R10: ffffc90001e67c10 R11: 0030ae0601000000 R12: 0000000000000000\n R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000000\n FS:  00007fde79159740(0000) GS:ffff88813bdc0000(0000) knlGS:0000000000000000\n CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 0000000020000180 CR3: 0000000105eb4005 CR4: 00000000003706b0\n DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n Call Trace:\n  \u003cTASK\u003e\n  ib_umem_odp_get+0x1f6/0x390\n  mlx5_ib_reg_user_mr+0x1e8/0x450\n  ib_uverbs_reg_mr+0x28b/0x440\n  ib_uverbs_write+0x7d3/0xa30\n  vfs_write+0x1ac/0x6c0\n  ksys_write+0x134/0x170\n  ?
