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-2026-98327 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-2026-98327/ (Markdown: https://insights.sbomify.com/CVE-2026-98327/index.md)","id":"CVE-2026-98327","markdown":"https://insights.sbomify.com/CVE-2026-98327/index.md","name":"CVE-2026-98327","record":{"aliases":["AZL-106248","BELL-CVE-2026-98327","DEBIAN-CVE-2026-98327","GHSA-6v32-hcc5-q9w8","UBUNTU-CVE-2026-98327"],"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":"none","summary":"A memory leak in the Linux kernel's mac80211 mesh networking code allows attackers to cause a denial of service by leaving a mesh network during a channel switch.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nwifi: mac80211: mesh: reset the CSA state when leaving\n\nifmsh-\u003ecsa is allocated in ieee80211_mesh_csa_beacon() and only freed\nin ieee80211_mesh_finish_csa(), i.e. when the channel switch completes.\nLeaving the mesh while a switch is still pending therefore leaks it.\n\nAdditionally, ifmsh-\u003ecsa_role and ifmsh-\u003echsw_ttl have their state leak\nin this case, so things can get mixed up in addition to the memory\nleak.\n\nRefactor the reset and call it in ieee80211_stop_mesh() to fix it all.","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":"wifi: mac80211: mesh: reset the CSA state when leaving","id":"CVE-2026-98327","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"wifi: mac80211: add HE 6 GHz capability in the scan elems len","id":"CVE-2026-98328"},"packages":[],"prev":{"headline":"wifi: mac80211: mesh: release the channel if start fails","id":"CVE-2026-98326"},"products":["Linux"],"published":"2026-10-06","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 memory leak in the Linux kernel's mac80211 mesh networking code allows attackers to cause a denial of service by leaving a mesh network during a channel switch.","url":"https://insights.sbomify.com/CVE-2026-98327/"}
