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-2025-37928 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-2025-37928/ (Markdown: https://insights.sbomify.com/CVE-2025-37928/index.md)","id":"CVE-2025-37928","markdown":"https://insights.sbomify.com/CVE-2025-37928/index.md","name":"CVE-2025-37928","record":{"aliases":["BELL-CVE-2025-37928","DEBIAN-CVE-2025-37928","GHSA-pq22-mrc2-gx83","ROOT-OS-DEBIAN-11-CVE-2025-37928","ROOT-OS-DEBIAN-12-CVE-2025-37928","ROOT-OS-UBUNTU-2204-CVE-2025-37928","ROOT-OS-UBUNTU-2404-CVE-2025-37928","UBUNTU-CVE-2025-37928"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A bug in the Linux kernel dm-bufio module causes a crash when scheduling occurs in atomic context, leading to 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":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm-bufio: don't schedule in atomic context\n\nA BUG was reported as below when CONFIG_DEBUG_ATOMIC_SLEEP and\ntry_verify_in_tasklet are enabled.\n[  129.444685][  T934] BUG: sleeping function called from invalid context at drivers/md/dm-bufio.c:2421\n[  129.444723][  T934] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 934, name: kworker/1:4\n[  129.444740][  T934] preempt_count: 201, expected: 0\n[  129.444756][  T934] RCU nest depth: 0, expected: 0\n[  129.444781][  T934] Preemption disabled at:\n[  129.444789][  T934] [\u003cffffffd816231900\u003e] shrink_work+0x21c/0x248\n[  129.445167][  T934] kernel BUG at kernel/sched/walt/walt_debug.c:16!\n[  129.445183][  T934] Internal error: Oops - BUG: 00000000f2000800 [#1] PREEMPT SMP\n[  129.445204][  T934] Skip md ftrace buffer dump for: 0x1609e0\n[  129.447348][  T934] CPU: 1 PID: 934 Comm: kworker/1:4 Tainted: G        W  OE      6.6.56-android15-8-o-g6f82312b30b9-debug #1 1400000003000000474e5500b3187743670464e8\n[  129.447362][  T934] Hardware name: Qualcomm Technologies, Inc.
