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-2026-53317 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-53317/ (Markdown: https://insights.sbomify.com/CVE-2026-53317/index.md)","id":"CVE-2026-53317","markdown":"https://insights.sbomify.com/CVE-2026-53317/index.md","name":"CVE-2026-53317","record":{"aliases":["AZL-92034","BELL-CVE-2026-53317","DEBIAN-CVE-2026-53317","GHSA-86cw-5chj-gj42","ROOT-OS-DEBIAN-12-CVE-2026-53317","ROOT-OS-UBUNTU-2204-CVE-2026-53317","ROOT-OS-UBUNTU-2404-CVE-2026-53317","UBUNTU-CVE-2026-53317"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel WiFi driver","requires_auth":"low_privilege","summary":"A missing upper limit on station AID in the mt7921 WiFi driver allows a remote attacker to crash the firmware via a modified hostapd, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7921: Place upper limit on station AID\n\nAny station configured with an AID over 20 causes a firmware crash.\nThis situation occurred in our testing using an AP interface on 7922\nhardware, with a modified hostapd, sourced from Mediatek's OpenWRT\nfeeds.\n\nIn stock hostapd, station AIDs begin counting at 1, and this\nconfiguration is prevented with an upper limit on associated stations.\nHowever, the modified hostapd began allocation at 65, which caused the\nfirmware to crash.
