like the htt pktlog sibling, triggering requires local suspend/resume on the ath11k host.\nAC:L - A local attacker can drive both sides of the missing-RCU race by inducing WoW resume (async getinfo status event) while concurrently stopping/rfkilling the radio so mac_op_stop clears pdevs_active without waiting for the unlocked reader.\nPR:L - Unlike pktlog (root-only debugfs), GTK offload status is reached through normal WoW suspend/resume on an already-associated STA, and a basic local seat user can suspend and rfkill/tear down wifi without real root; choose Low over High under uncertainty.\nUI:N - The attacker triggers suspend/resume and concurrent radio teardown themselves; no separate victim action such as mounting a device or opening a file is required.\nS:U - Any use-after-free or crash remains inside the host kernel ath11k/mac80211 authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - Missing rcu_read_lock around ath11k_mac_get_arvif_by_vdev_id() allows use of RCU-protected pdev/arvif state after deactivation/teardown; per guidance that UAF enables heap reuse and arbitrary kernel disclosure.\nI:H - The same UAF of sprayable ath11k/ieee80211 state while the handler still writes arvif->rekey_data and calls ieee80211_gtk_rekey_notify() yields write/control-flow primitives characteristic of exploitable kernel UAFs.\nA:H - Concurrent use of deactivated or freed ar/arvif after synchronize_rcu without a matching read-side critical section can oops/panic the kernel, so availability impact is complete even without full code execution." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/ath11k/wmi.c" ], "versions": [ { "version": "a16d9b50cfbaf112401b8e5ccfa852709f498cd4", "lessThan": "0cf7577b6b3153b4b49deea9719fe43f96469c6d", "status": "affected", "versionType": "git" }, { "version": "a16d9b50cfbaf112401b8e5ccfa852709f498cd4", "lessThan": "cf9c7d783a2bf9305df4ef5b93d9063a52e18fca", "status": "affected", "versionType": "git" }, { "version": "a16d9b50cfbaf112401b8e5ccfa852709f498cd4", "lessThan": "e83246ecd3b193f8d91fce778e8a5ba747fc7d8a", "status": "affected", "versionType": "git" }, { "version": "a16d9b50cfbaf112401b8e5ccfa852709f498cd4", "lessThan": "1dea3c0720a146bd7193969f2847ccfed5be2221", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/ath11k/wmi.c" ], "versions": [ { "version": "5.19", "status": "affected" }, { "version": "0", "lessThan": "5.19", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.64", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.5.13", "lessThanOrEqual": "6.5.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.3", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.1.64" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.5.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.6.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.7" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/0cf7577b6b3153b4b49deea9719fe43f96469c6d" }, { "url": "https://git.kernel.org/stable/c/cf9c7d783a2bf9305df4ef5b93d9063a52e18fca" }, { "url": "https://git.kernel.org/stable/c/e83246ecd3b193f8d91fce778e8a5ba747fc7d8a" }, { "url": "https://git.kernel.org/stable/c/1dea3c0720a146bd7193969f2847ccfed5be2221" } ], "title": "wifi: ath11k: fix gtk offload status event locking", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-06-11T19:02:33.104865Z", "id": "CVE-2023-52777", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-11T19:03:07.955Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T23:11:36.014Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/0cf7577b6b3153b4b49deea9719fe43f96469c6d", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/cf9c7d783a2bf9305df4ef5b93d9063a52e18fca", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/e83246ecd3b193f8d91fce778e8a5ba747fc7d8a", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/1dea3c0720a146bd7193969f2847ccfed5be2221", "tags": [ "x_transferred" ] } ] } ] } }
