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-2026-98553 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-2026-98553/ (Markdown: https://insights.sbomify.com/CVE-2026-98553/index.md)","id":"CVE-2026-98553","markdown":"https://insights.sbomify.com/CVE-2026-98553/index.md","name":"CVE-2026-98553","record":{"aliases":["AZL-108863","BELL-CVE-2026-98553","DEBIAN-CVE-2026-98553","GHSA-j44w-wp8g-33m4","UBUNTU-CVE-2026-98553"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A resource leak in the Linux kernel autofs module allows local attackers to exhaust system memory, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nautofs: fix sbi-\u003epipe file reference leak in autofs_kill_sb()\n\nWhen autofs_fill_super() fails before clearing AUTOFS_SBI_CATATONIC (for\nexample, when find_get_pid() fails on an invalid pgrp mount option, or\nwhen an fs_context is closed before mounting), deactivate_locked_super()\ninvokes autofs_kill_sb() -\u003e autofs_catatonic_mode(sbi).\n\nBecause AUTOFS_SBI_CATATONIC is still set in sbi-\u003eflags,\nautofs_catatonic_mode() returns early without calling fput(sbi-\u003epipe),\npermanently leaking the pipe struct file reference.\n\nExplicitly release sbi-\u003epipe in autofs_kill_sb() if it is still non-NULL\nafter autofs_catatonic_mode().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"autofs: fix sbi-\u003epipe file reference leak in autofs_kill_sb()","id":"CVE-2026-98553","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"vlan: ensure sufficient headroom in vlan_dev_hard_header()","id":"CVE-2026-98554"},"packages":[],"prev":{"headline":"perf/core: Fix a refcount leak in attach_perf_ctx_data()","id":"CVE-2026-98552"},"products":["Linux"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A resource leak in the Linux kernel autofs module allows local attackers to exhaust system memory, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-98553/"}
