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-2025-38636 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-2025-38636/ (Markdown: https://insights.sbomify.com/CVE-2025-38636/index.md)","id":"CVE-2025-38636","markdown":"https://insights.sbomify.com/CVE-2025-38636/index.md","name":"CVE-2025-38636","record":{"aliases":["AZL-66611","BELL-CVE-2025-38636","DEBIAN-CVE-2025-38636","GHSA-xg28-vm4v-pcgp","ROOT-OS-DEBIAN-12-CVE-2025-38636","ROOT-OS-DEBIAN-13-CVE-2025-38636","ROOT-OS-UBUNTU-2404-CVE-2025-38636","UBUNTU-CVE-2025-38636"],"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 kernel bug causes out-of-bounds reads in tracepoints when KASAN is enabled, potentially leading to system crashes or instability.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nrv: Use strings in da monitors tracepoints\n\nUsing DA monitors tracepoints with KASAN enabled triggers the following\nwarning:\n\n BUG: KASAN: global-out-of-bounds in do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0\n Read of size 32 at addr ffffffffaada8980 by task ...\n Call Trace:\n  \u003cTASK\u003e\n [...]\n  do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0\n  ? __pfx_do_trace_event_raw_event_event_da_monitor+0x10/0x10\n  ? trace_event_sncid+0x83/0x200\n  trace_event_sncid+0x163/0x200\n [...]\n The buggy address belongs to the variable:\n  automaton_snep+0x4e0/0x5e0\n\nThis is caused by the tracepoints reading 32 bytes __array instead of\n__string from the automata definition.
