{"schema":"threatline.record/2","record":{"id":"CVE-2026-99060","aliases":[],"summary":"wifi: mt76: mt7603: initialize global station WCID","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7603: initialize global station WCID\n\nmt7603 uses a driver-private global station WCID for frames that have\nneither a station nor a vif, including frames injected through a monitor\ninterface. Unlike the core global WCID initialized by\nmt76_register_device(), this WCID is published without ever being passed\nto mt76_wcid_init().\n\nSince commit 0335c034e726 (\"wifi: mt76: fix race condition related to\nchecking tx queue fill status\"), mt76_tx() queues every such frame on the\nWCID's tx_pending or tx_offchannel queue and links its tx_list. The first\ninjected frame therefore reaches __skb_queue_tail() with an uninitialized\nsk_buff_head and dereferences a NULL prev pointer.\n\nInitialize the WCID before publishing it.\n\nThe fix was tested on an MT7603 PCIe device. Three wildcard probe requests\nwere injected through a monitor interface. The hardware queue head and tail\nadvanced from 0 to 3 and a second radio captured the third request over the\nair. No oops or reset occurred. After restoring AP mode, a 150 MB transfer\nalso completed without a reset.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"d2defcddfe90b3be0cfccc2482495ab1fb759586","lessThan":"99b8bd6323e6fc69615af828522878b7acb77bff","status":"affected","versionType":"git"},{"version":"0335c034e7265d36d956e806f33202c94a8a9860","lessThan":"e454ec553996f21085657c96c8a605e2d89a81a6","status":"affected","versionType":"git"},{"version":"0335c034e7265d36d956e806f33202c94a8a9860","lessThan":"dd117d17e8aa2e89f857fb708e5b770709fb81cb","status":"affected","versionType":"git"},{"version":"0335c034e7265d36d956e806f33202c94a8a9860","lessThan":"19d6fa087dcf242223645828b8282d4040bad168","status":"affected","versionType":"git"},{"version":"0335c034e7265d36d956e806f33202c94a8a9860","lessThan":"456de496b53ae73e6e3020fec815dbdc88aa7c07","status":"affected","versionType":"git"},{"version":"6.6.48","lessThan":"6.6.160","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","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":"6.18.57","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.11","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-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"99b8bd6323e6fc69615af828522878b7acb77bff","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"19d6fa087dcf242223645828b8282d4040bad168","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"456de496b53ae73e6e3020fec815dbdc88aa7c07","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","source_modified_at":"2026-10-23T12:22:49.164Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"6.6.160","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:22:49.164Z","modified_at":"2026-10-23T12:22:49.164Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99060","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:22:49.164Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/99b8bd6323e6fc69615af828522878b7acb77bff"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e454ec553996f21085657c96c8a605e2d89a81a6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/dd117d17e8aa2e89f857fb708e5b770709fb81cb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/19d6fa087dcf242223645828b8282d4040bad168"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/456de496b53ae73e6e3020fec815dbdc88aa7c07"}],"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":"2026-10-23T12:22:49.164Z","content_hash":"e3b30b4c78021b7adf43b6408302230d4a6726eda74ceae97e9f74e8065e6597"}}
