When num_twt_flows exceeds 8, the handler writes past the destination array (which is typically on the caller's stack, e.g. the wifi ps shell command) -- an out-of-bounds write of ~40-byte TWT entries -- and reads twt_flow_info[i] past the event buffer. The event is delivered by the nRF70 co-processor firmware in response to a host-initiated power-save GET, so reaching the overflow requires the firmware to emit a malformed or out-of-range event; the trust boundary is host-to-trusted-coprocessor rather than a direct remote-AP write, with over-the-air influence on the flow count being indirect and bounded by the 3-bit TWT flow-id space. Affected: builds with CONFIG_NRF70_STA_MODE on releases through v4.4.0. The fix rejects events with num_twt_flows > WIFI_MAX_TWT_FLOWS or with event_len shorter than the claimed entries, and adds a NULL check on the caller buffer.","epss":{"date":"2026-11-03","percentile":0.12935,"score":0.00223},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"},{"kind":"exploit","source":"vulnerabilities@zephyrproject.org","url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"},{"kind":"exploit","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"}],"kev":null,"metrics":[{"score":5,"severity":"medium","source":"CNA: zephyr","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},{"score":5,"severity":"medium","source":"NVD: vulnerabilities@zephyrproject.org","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"}],"modifiedAt":1793769504747,"publishedAt":1783873009115,"references":[{"source":"CNA: zephyr","tags":["patch"],"url":"https://github.com/zephyrproject-rtos/zephyr/commit/a2c4324acd50a5f92e492e6e460e6297af826148"},{"source":"CNA: zephyr","tags":[],"url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"},{"source":"vulnerabilities@zephyrproject.org","tags":["Patch"],"url":"https://github.com/zephyrproject-rtos/zephyr/commit/a2c4324acd50a5f92e492e6e460e6297af826148"},{"source":"vulnerabilities@zephyrproject.org","tags":["Exploit","Mitigation","Patch","Vendor Advisory"],"url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Mitigation","Patch","Vendor Advisory"],"url":"https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-3r6j-pm38-r43m"}],"remediation":[{"kind":"fix","source":"CNA: zephyr","text":"The reporting source identifies this reference as a patch.
