Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
IOCTL exploitation requires local low-privilege process access (AV:L, PR:L); no special configuration needed (AC:L); kernel memory corruption yields full C/I/A impact with no scope change.

Memory Corruption while processing IOCTL device driver requests with invalid arguments.
AnalysisAI
Memory corruption in Qualcomm Snapdragon IOCTL device driver handling enables a local low-privilege attacker to achieve full confidentiality, integrity, and availability impact on the affected system. The flaw (CWE-822: Untrusted Pointer Dereference) allows a process to supply invalid pointer arguments via IOCTL calls that the driver dereferences without adequate validation, corrupting kernel memory. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to already have low-privilege code execution on the target device (CVSS PR:L, AV:L) - for example, via an installed malicious application or a separate initial-access vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (High) is grounded in a local attack vector (AV:L), low complexity (AC:L), low privilege (PR:L), no user interaction (UI:N), unchanged scope (S:U), and full C/H/I:H/A:H impact - a profile typical of local privilege escalation to kernel. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A malicious Android application installed on a Snapdragon-based device opens the affected kernel driver's device node and issues a crafted IOCTL call with deliberately invalid pointer arguments. The driver dereferences the untrusted pointer in kernel context without validation, triggering memory corruption that the attacker shapes into a controlled write primitive. … |
| Remediation | The primary remediation is to apply the patch detailed in Qualcomm's August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all devices running vulnerable Snapdragon IOCTL drivers in production inventory using vulnerability scanning or device management platforms, and assess exposure levels based on user privilege models in your environment. …
