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-2025-38581 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-2025-38581/ (Markdown: https://insights.sbomify.com/CVE-2025-38581/index.md)","id":"CVE-2025-38581","markdown":"https://insights.sbomify.com/CVE-2025-38581/index.md","name":"CVE-2025-38581","record":{"aliases":["AZL-66500","BELL-CVE-2025-38581","DEBIAN-CVE-2025-38581","GHSA-p2qj-w526-vfr2","OESA-2025-2123","ROOT-OS-DEBIAN-11-CVE-2025-38581","ROOT-OS-DEBIAN-12-CVE-2025-38581","ROOT-OS-DEBIAN-13-CVE-2025-38581","ROOT-OS-UBUNTU-2204-CVE-2025-38581","ROOT-OS-UBUNTU-2404-CVE-2025-38581","UBUNTU-CVE-2025-38581"],"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 local attacker can cause a kernel crash by rebinding the CCP device when debugfs is enabled, leading to denial of service.","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\ncrypto: ccp - Fix crash when rebind ccp device for ccp.ko\n\nWhen CONFIG_CRYPTO_DEV_CCP_DEBUGFS is enabled, rebinding\nthe ccp device causes the following crash:\n\n$ echo '0000:0a:00.2' \u003e /sys/bus/pci/drivers/ccp/unbind\n$ echo '0000:0a:00.2' \u003e /sys/bus/pci/drivers/ccp/bind\n\n[  204.976930] BUG: kernel NULL pointer dereference, address: 0000000000000098\n[  204.978026] #PF: supervisor write access in kernel mode\n[  204.979126] #PF: error_code(0x0002) - not-present page\n[  204.980226] PGD 0 P4D 0\n[  204.981317] Oops: Oops: 0002 [#1] SMP NOPTI\n...\n[  204.997852] Call Trace:\n[  204.999074]  \u003cTASK\u003e\n[  205.000297]  start_creating+0x9f/0x1c0\n[  205.001533]  debugfs_create_dir+0x1f/0x170\n[  205.002769]  ?
