Severity by source
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Local-only driver interface (AV:L); concurrency race needing a timing window (AC:H); DMA ioctl surface typically reachable by low-privileged local processes (PR:L); full kernel memory corruption gives high C/I/A.

Memory Corruption when processing concurrent DMA buffer allocation and deallocation commands without proper synchronization.
AnalysisAI
A use-after-free (CWE-416) in Qualcomm Snapdragon's DMA buffer management allows a local attacker with low privileges to corrupt kernel memory by triggering a race condition between concurrent DMA buffer allocation and deallocation, potentially leading to code execution or privilege escalation. The vulnerability is not remotely exploitable and requires winning a timing window (AC:H). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution on a Qualcomm Snapdragon device and the ability to issue DMA buffer allocation and deallocation commands to the affected kernel driver concurrently from at least two execution contexts (threads/processes) to trigger the unsynchronized use-after-free. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, base 6.7, MEDIUM) describes a local, high-privilege use-after-free (CWE-416) in Qualcomm Snapdragon DMA buffer management. … 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 | Patch availability is indicated in the Qualcomm October 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2026-bulletin.html); apply the vendor-provided update for your specific chipset and firmware. … Detailed patch versions, workarounds, and compensating controls in full report. |
