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-2025-37781 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-2025-37781/ (Markdown: https://insights.sbomify.com/CVE-2025-37781/index.md)","id":"CVE-2025-37781","markdown":"https://insights.sbomify.com/CVE-2025-37781/index.md","name":"CVE-2025-37781","record":{"aliases":["BELL-CVE-2025-37781","DEBIAN-CVE-2025-37781","GHSA-mrq3-qx26-xjxj","ROOT-OS-DEBIAN-12-CVE-2025-37781","ROOT-OS-UBUNTU-2204-CVE-2025-37781","ROOT-OS-UBUNTU-2404-CVE-2025-37781","UBUNTU-CVE-2025-37781"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A NULL pointer dereference in the Linux kernel's cros-ec-tunnel driver causes a system crash when the parent EC device is missing.","user_interaction":"not_required","vuln_class":"null_dereference"},"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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: cros-ec-tunnel: defer probe if parent EC is not present\n\nWhen i2c-cros-ec-tunnel and the EC driver are built-in, the EC parent\ndevice will not be found, leading to NULL pointer dereference.\n\nThat can also be reproduced by unbinding the controller driver and then\nloading i2c-cros-ec-tunnel module (or binding the device).\n\n[  271.991245] BUG: kernel NULL pointer dereference, address: 0000000000000058\n[  271.998215] #PF: supervisor read access in kernel mode\n[  272.003351] #PF: error_code(0x0000) - not-present page\n[  272.008485] PGD 0 P4D 0\n[  272.011022] Oops: Oops: 0000 [#1] SMP NOPTI\n[  272.015207] CPU: 0 UID: 0 PID: 3859 Comm: insmod Tainted: G S                  6.15.0-rc1-00004-g44722359ed83 #30 PREEMPT(full)  3c7fb39a552e7d949de2ad921a7d6588d3a4fdc5\n[  272.030312] Tainted: [S]=CPU_OUT_OF_SPEC\n[  272.034233] Hardware name: HP Berknip/Berknip, BIOS Google_Berknip.13434.356.0 05/17/2021\n[  272.042400] RIP: 0010:ec_i2c_probe+0x2b/0x1c0 [i2c_cros_ec_tunnel]\n[  272.048577] Code: 1f 44 00 00 41 57 41 56 41 55 41 54 53 48 83 ec 10 65 48 8b 05 06 a0 6c e7 48 89 44 24 08 4c 8d 7f 10 48 8b 47 50 4c 8b 60 78 \u003c49\u003e 83 7c 24 58 00 0f 84 2f 01 00 00 48 89 fb be 30 06 00 00 4c 9\n[  272.067317] RSP: 0018:ffffa32082a03940 EFLAGS: 00010282\n[  272.072541] RAX: ffff969580b6a810 RBX: ffff969580b68c10 RCX: 0000000000000000\n[  272.079672] RDX: 0000000000000000 RSI: 0000000000000282 RDI: ffff969580b68c00\n[  272.086804] RBP: 00000000fffffdfb R08: 0000000000000000 R09: 0000000000000000\n[  272.093936] R10: 0000000000000000 R11: ffffffffc0600000 R12: 0000000000000000\n[  272.101067] R13: ffffffffa666fbb8 R14: ffffffffc05b5528 R15: ffff969580b68c10\n[  272.108198] FS:  00007b930906fc40(0000) GS:ffff969603149000(0000) knlGS:0000000000000000\n[  272.116282] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  272.122024] CR2: 0000000000000058 CR3: 000000012631c000 CR4: 00000000003506f0\n[  272.129155] Call Trace:\n[  272.131606]  \u003cTASK\u003e\n[  272.133709]  ?
