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"]}]}]}}
