AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Adjacent wireless vector with no auth required; integer underflow yields memory read only, so I:N and A:N are appropriate.

Information Disclosure when processing wireless network channel switch information with improperly formatted length fields.
AnalysisAI
Information disclosure in Qualcomm Snapdragon wireless subsystem allows an adjacent-network attacker to leak sensitive memory contents by transmitting malformed wireless channel switch frames with invalid length fields. The root cause is CWE-191 (integer underflow), where improperly formatted length values trigger an arithmetic wrap condition during 802.11 management frame parsing, resulting in out-of-bounds memory reads. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target device must have its WiFi interface active and the attacker must be within radio range or operating a rogue access point that the device processes frames from. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N yields a score of 6.5 (Medium), which is directionally reasonable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker positions a rogue access point or an attacker-controlled device within radio range of a target Snapdragon-equipped device, then transmits crafted 802.11 management frames containing channel switch information elements with deliberately underflowing length fields. The integer underflow causes the Snapdragon WLAN stack to read beyond the intended buffer, leaking adjacent memory contents - which may include cryptographic material, session tokens, or other sensitive data - back to the attacker. … |
| Remediation | Consult the Qualcomm August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html) to identify exact patched firmware or driver versions for your specific Snapdragon SKU. … Detailed patch versions, workarounds, and compensating controls in full report. |
