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 root cause makes reliable triggering timing-dependent, so AC:H; use-after-free yields full C:H/I:H/A:H.

Memory corruption when performing concurrent operations on shared memory page lists due to lack of proper synchronization mechanisms.
AnalysisAI
Use-after-free memory corruption affecting Qualcomm Snapdragon platforms lets a local, low-privileged attacker (PR:L, AV:L, UI:N) trigger concurrent operations on shared memory page lists that are not properly synchronized, potentially reusing freed memory and gaining high impact to confidentiality, integrity, and availability. Because the root cause is a race condition (CWE-416), exploitation is timing-dependent and may require repeated attempts; the attacker must already have code running on the device, so there is no remote or network attack path. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local, low-privileged code execution on the affected Snapdragon device (PR:L, AV:L, UI:N) - for example a malicious or compromised third-party application interacting with the vulnerable driver/memory subsystem. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a CWE-416 use-after-free / memory-corruption flaw in Qualcomm Snapdragon platforms, caused by missing synchronization during concurrent operations on shared memory page lists. … 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 | Apply the fixes referenced in the Qualcomm October 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2026-bulletin.html) by updating to the patched Snapdragon firmware/BSP version listed there; because Qualcomm supplies silicon, the usable patch reaches devices only through OEM firmware and carrier updates, so track and install the corresponding vendor build for each affected handset, tablet, automotive, or IoT product - the exact patched build string is not enumerated in the available data and should be confirmed with the OEM. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Qualcomm Snapdragon-based devices (e.g., Android smartphones/tablets, Windows on Snapdragon laptops, IoT/embedded systems) and review the October 2026 Qualcomm security bulletin for the affected chipset list and any exact fix version when released; enforce existing mobile threat defense, restrict developer options and sideloading, and monitor for local privilege escalation or abnormal process behavior. …
