Severity by source
AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Local attacker with an app-level foothold (AV:L/PR:L) must win a non-deterministic IOCTL race (AC:H); memory corruption in the driver yields full C/I/A impact.

Memory Corruption when multiple threads issue concurrent IOCTL requests to the device control handler due to improper synchronization and race conditions.
AnalysisAI
Memory corruption in the Qualcomm Snapdragon device-control handler can be triggered when multiple threads of a local, low-privilege process open the driver and issue concurrent IOCTL requests, exposing the driver to an improper-synchronization race that can corrupt memory and, in the worst case, allow code execution at the privilege level of the driver (C:H/I:H/A:H). Exploitation is not remote and is not automated: the attacker must already hold local low-privilege code execution on the affected device (AV:L, PR:L), must be able to reach the device-control handler, and must win a non-deterministic inter-thread race (AC:H; SSVC Automatable: no). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires the attacker to already have local, low-privilege code execution on the affected Snapdragon device (AV:L, PR:L) - for example a running app - and the ability to open the vulnerable device-control handler and issue IOCTLs to it. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but not urgent priority. … 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 | Primary fix: obtain and flash the firmware/driver update published in the Qualcomm September 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html), which is the vendor advisory of record and maps each affected chipset to its fixed build; no explicit fixed version number is provided in the available input data, so OEMs and device maintainers should confirm the exact patched driver build against that bulletin and the matching NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-24075) before certifying remediation. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, confirm whether the organization ships or manages devices using affected Qualcomm Snapdragon platforms and whether the device-control handler is reachable from low-privilege contexts; inventory firmware and driver versions and contact Qualcomm and OEM partners for advisory status, since no vendor-released patch has been identified at time of analysis. …
