{"schema":"threatline.record/2","record":{"id":"CVE-2026-98705","aliases":[],"summary":"wifi: mac80211: account proxy paths against the mesh path limit","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: account proxy paths against the mesh path limit\n\nProxy-path churn can drive the interface path counter negative and let\nlater mesh path additions exceed MESH_MAX_MPATHS.\n\nmesh_path_free_rcu() decrements the interface mpaths counter for entries\nfrom both the mesh and proxy path tables, but mpp_path_add() never\nreserves a slot in that counter. Removing or expiring a proxy path\ntherefore returns a slot that was never charged.\n\nmesh_path_add() uses the same counter to enforce MESH_MAX_MPATHS, so once\nit falls below the number of installed paths the limit no longer holds.\n\nReserve the shared quota before allocating a proxy path and release it on\nevery unsuccessful addition. Mesh and proxy paths now share one\n1024-entry budget, so mpp_path_add() can return -ENOSPC at that limit.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98705","source_modified_at":"2026-10-21T12:55:53.953Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"c66ab4b94bb04c162485759196555e08c0965320","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"df072db65fdaa34ad15e1d66fc06a53e3e97f778","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"3b75831ceee76d32bb8e7ddd241904f92f9b5407","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"5a32409ed34a1868830899a5d2437f0b3bf3532c","status":"affected","versionType":"git"},{"version":"ece1a2e7e86078c8379937b546e32cb7f25fcb6c","lessThan":"a5f35d4b112af1415ff06bd501c8cc26cc08aa8b","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98705","source_modified_at":"2026-10-21T12:55:53.953Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.2","status":"affected"},{"version":"0","lessThan":"3.2","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98705","source_modified_at":"2026-10-21T12:55:53.953Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"3b75831ceee76d32bb8e7ddd241904f92f9b5407","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98705","source_modified_at":"2026-10-21T12:55:53.953Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5a32409ed34a1868830899a5d2437f0b3bf3532c","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09312,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:46:35.520Z","modified_at":"2026-10-21T12:55:53.953Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98705","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:55:53.953Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98705","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/c66ab4b94bb04c162485759196555e08c0965320"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/df072db65fdaa34ad15e1d66fc06a53e3e97f778"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/3b75831ceee76d32bb8e7ddd241904f92f9b5407"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/5a32409ed34a1868830899a5d2437f0b3bf3532c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a5f35d4b112af1415ff06bd501c8cc26cc08aa8b"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:55:53.953Z","content_hash":"8928944436cc43bbc228639d35cf546d9be2ac8a8eeb555c5d8f2531dac8a298"}}
