An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74427 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-2026-74427/ (Markdown: https://insights.sbomify.com/CVE-2026-74427/index.md)","id":"CVE-2026-74427","markdown":"https://insights.sbomify.com/CVE-2026-74427/index.md","name":"CVE-2026-74427","record":{"aliases":["BELL-CVE-2026-74427","DEBIAN-CVE-2026-74427","GHSA-2hj8-22xr-w775","UBUNTU-CVE-2026-74427"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel AFS","requires_auth":"none","summary":"A race condition in Linux kernel AFS network namespace teardown can cause a denial of service by failing to cancel preallocation work items.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\nafs: Fix netns teardown to cancel the preallocation charger\n\nFix the teardown of an afs network namespace to make sure it cancels the\nwork item that keeps the preallocated rxrpc call/conn/peer queue charged\nbefore incoming calls are disabled (i.e. listen 0).\n\nAlso, if net-\u003elive is false because the afs netns is being deleted, make\nafs_charge_preallocation() skip charging and make afs_rx_new_call() avoid\nrequeuing the charger.\n\n(This was found by AI review).","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":"afs: Fix netns teardown to cancel the preallocation charger","id":"CVE-2026-74427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"rxrpc: Fix double unlock in rxrpc_recvmsg()","id":"CVE-2026-74428"},"packages":[],"prev":{"headline":"afs: fix NULL pointer dereference in afs_get_tree()","id":"CVE-2026-74426"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A race condition in Linux kernel AFS network namespace teardown can cause a denial of service by failing to cancel preallocation work items.","url":"https://insights.sbomify.com/CVE-2026-74427/"}
