maintainers confirmed this occurs in real usage, so no attacker-uncontrollable race or rare config is required.\\nPR:N - RX airtime accounting runs on frames addressed to the device MAC without authentication or local credentials; an unauthenticated adjacent WiFi peer can trigger the path.\\nUI:N - No victim action is required beyond normal WiFi operation; the attacker only needs to exchange or inject frames on the wireless link.\\nS:U - Impact is confined to the host kernel\\u2019s airtime accounting and memory access within the same security authority; there is no VM/IOMMU/sandbox boundary crossing.\\nC:H - This is an out-of-bounds read of kernel memory past duration[MCS_GROUP_RATES]; per scoring guidance, OOB reads are C:H unless strictly limited to a few bytes, and rate_idx is a u8 on HE paths so the read is not tightly bounded on all call paths.\\nI:N - The bug only reads a const duration table into a local airtime value; it does not write attacker-controlled data or provide a memory-corruption write/code-execution primitive.\\nA:H - Out-of-bounds kernel reads can fault or oops when the index falls outside mapped rodata (especially for larger rate_idx values), and when crash potential is uncertain the higher availability impact is required.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"db3e1c40cf2f973fbdd52ae0b59a9472b1c04f4a\", \"lessThan\": \"0184ede0ec61b9cd075babfaa45081b1bf322234\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"db3e1c40cf2f973fbdd52ae0b59a9472b1c04f4a\", \"lessThan\": \"59b54f0563b6546c94bdb6823d3b382c75407019\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"db3e1c40cf2f973fbdd52ae0b59a9472b1c04f4a\", \"lessThan\": \"f0fcad4c7201ecfaa17357f4ce0c50b4708df22d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"db3e1c40cf2f973fbdd52ae0b59a9472b1c04f4a\", \"lessThan\": \"3e8f7abcc3473bc9603323803aeaed4ffcc3a2ab\", \"versionType\": \"git\"}], \"programFiles\": [\"net/mac80211/airtime.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.5\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.5\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.158\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.82\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.0.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.0.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/mac80211/airtime.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/0184ede0ec61b9cd075babfaa45081b1bf322234\"}, {\"url\": \"https://git.kernel.org/stable/c/59b54f0563b6546c94bdb6823d3b382c75407019\"}, {\"url\": \"https://git.kernel.org/stable/c/f0fcad4c7201ecfaa17357f4ce0c50b4708df22d\"}, {\"url\": \"https://git.kernel.org/stable/c/3e8f7abcc3473bc9603323803aeaed4ffcc3a2ab\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nwifi: mac8021: fix possible oob access in ieee80211_get_rate_duration\\n\\nFix possible out-of-bound access in ieee80211_get_rate_duration routine\\nas reported by the following UBSAN report:\\n\\nUBSAN: array-index-out-of-bounds in net/mac80211/airtime.c:455:47\\nindex 15 is out of range for type \u0027u16 [12]\u0027\\nCPU: 2 PID: 217 Comm: kworker/u32:10 Not tainted 6.1.0-060100rc3-generic\\nHardware name: Acer Aspire TC-281/Aspire TC-281, BIOS R01-A2 07/18/2017\\nWorkqueue: mt76 mt76u_tx_status_data [mt76_usb]\\nCall Trace:\\n \u003cTASK\u003e\\n show_stack+0x4e/0x61\\n dump_stack_lvl+0x4a/0x6f\\n dump_stack+0x10/0x18\\n ubsan_epilogue+0x9/0x43\\n __ubsan_handle_out_of_bounds.cold+0x42/0x47\\nieee80211_get_rate_duration.constprop.0+0x22f/0x2a0 [mac80211]\\n ? ieee80211_tx_status_ext+0x32e/0x640 [mac80211]\\n ieee80211_calc_rx_airtime+0xda/0x120 [mac80211]\\n ieee80211_calc_tx_airtime+0xb4/0x100 [mac80211]\\n mt76x02_send_tx_status+0x266/0x480 [mt76x02_lib]\\n mt76x02_tx_status_data+0x52/0x80 [mt76x02_lib]\\n mt76u_tx_status_data+0x67/0xd0 [mt76_usb]\\n process_one_work+0x225/0x400\\n worker_thread+0x50/0x3e0\\n ? process_one_work+0x400/0x400\\n kthread+0xe9/0x110\\n ? kthread_complete_and_exit+0x20/0x20\\n ret_from_fork+0x22/0x30\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.158\", \"versionStartIncluding\": \"5.5\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.82\", \"versionStartIncluding\": \"5.5\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.0.12\", \"versionStartIncluding\": \"5.5\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1\", \"versionStartIncluding\": \"5.5\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T08:53:29.205Z\"}}}",
