Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local app-level access gives AV:L/PR:L; the concurrency race condition makes reliable triggering AC:H; memory corruption yields full C:H/I:H/A:H with scope unchanged.

Memory Corruption when accessing and modifying geographic mapping data concurrently without proper synchronization.
AnalysisAI
Use-after-free memory corruption in Qualcomm Snapdragon components allows a local, low-privileged attacker who already holds code execution on the device - for example through a malicious or compromised app - to corrupt memory and potentially achieve code execution or privilege escalation in the context of the affected component, with high confidentiality, integrity, and availability impact. Triggering the flaw requires winning a race between concurrent operations that access and modify geographic mapping data without proper synchronization, a timing dependency our assessment scores as AC:H rather than the base AC:L, which makes reliable exploitation non-deterministic. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to already have local, low-privileged code execution on a device using an affected Qualcomm Snapdragon component (AV:L, PR:L, UI:N) - for example a malicious or compromised app. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The base CVSS of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a high-impact local memory-corruption flaw (CWE-416, use-after-free via a concurrency/race condition) in Qualcomm Snapdragon components, but several real-world-risk signals temper this. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No specific fixed version is identified in the available data, so patch status should be treated as "patch availability not confirmed from the provided data" and the Qualcomm October 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2026-bulletin.html) together with the relevant OEM's build notes must be checked for the exact remediated component version before claiming a fix; do not assume a version number that is not published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Snapdragon-based endpoints in your fleet (Android, Windows on ARM, Chromebooks, IoT/embedded systems) and confirm whether any allow sideloading or untrusted app installation; enforce mobile device management policies to block untrusted sources and restrict developer options. …
