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-2026-72177 in the wild and no public exploit code.\n\nAffected product: 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-2026-72177/ (Markdown: https://insights.sbomify.com/CVE-2026-72177/index.md)","id":"CVE-2026-72177","markdown":"https://insights.sbomify.com/CVE-2026-72177/index.md","name":"CVE-2026-72177","record":{"aliases":["BELL-CVE-2026-72177","DEBIAN-CVE-2026-72177","GHSA-6mfj-xx36-5894","UBUNTU-CVE-2026-72177"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can trigger uninitialized memory dereference or memory leaks in the Linux kernel DAMON sysfs interface, potentially causing system crashes.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/sysfs-schemes: fix dir put orders in access_pattern_add_dirs()\n\nPatch series \"mm/damon/sysfs-schemes: fix wrong directories put orders in\nerror paths\".\n\nError paths of damon_sysfs_access_pattern_add_dirs() and\ndamon_sysfs_scheme_add_dirs() functions put references to directories in\nwrong orders.
