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-2026-98335 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-2026-98335/ (Markdown: https://insights.sbomify.com/CVE-2026-98335/index.md)","id":"CVE-2026-98335","markdown":"https://insights.sbomify.com/CVE-2026-98335/index.md","name":"CVE-2026-98335","record":{"aliases":["AZL-106065","BELL-CVE-2026-98335","DEBIAN-CVE-2026-98335","GHSA-wmxc-8xr9-g2qr","UBUNTU-CVE-2026-98335"],"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 null pointer dereference in the Linux kernel's mac80211 mesh networking code causes a system crash when leaving a mesh network during a channel switch.","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\nwifi: mac80211: abort chanswitch when leaving a mesh\n\nThe code in ieee80211_stop_mesh() leaves CSA active, but leaving\nthe mesh released the channel context, so the CSA finalize work\ncrashes:\n\n  Oops: general protection fault, probably for non-canonical address\n        0xdffffc0000000003\n  KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f]\n  RIP: 0010:ieee80211_put_srates_elem+0x42/0x640 net/mac80211/util.c:3272\n  Call Trace:\n   ieee80211_mesh_build_beacon+0xa83/0x1b50 net/mac80211/mesh.c:1093\n   ieee80211_mesh_rebuild_beacon+0xc7/0x170 net/mac80211/mesh.c:1147\n   ieee80211_mesh_finish_csa+0x131/0x210 net/mac80211/mesh.c:1542\n   ieee80211_set_after_csa_beacon net/mac80211/cfg.c:4085 [inline]\n   __ieee80211_csa_finalize net/mac80211/cfg.c:4133 [inline]\n   ieee80211_csa_finalize+0x633/0x1150 net/mac80211/cfg.c:4155\n   cfg80211_wiphy_work+0x2ab/0x450 net/wireless/core.c:438\n\nAbort the channel switch properly.","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: abort chanswitch when leaving a mesh","id":"CVE-2026-98335","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"wifi: mac80211: don't offload TC setup on AP_VLAN interfaces","id":"CVE-2026-98336"},"packages":[],"prev":{"headline":"wifi: mac80211: reset state when starting AP fails","id":"CVE-2026-98334"},"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 null pointer dereference in the Linux kernel's mac80211 mesh networking code causes a system crash when leaving a mesh network during a channel switch.","url":"https://insights.sbomify.com/CVE-2026-98335/"}
