Severity by source
AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Local privilege escalation requiring existing low-privilege access (AV:L, PR:L); weak extraction config is trivially abused (AC:L) and crosses a privilege boundary (S:C) yielding full CIA impact.

Privilege escalation due to weak configuration during package extraction process.
AnalysisAI
Privilege escalation in Qualcomm Snapdragon devices allows a local low-privilege attacker to cross security boundaries and gain full control over confidentiality, integrity, and availability (CVSS 8.8). The flaw stems from a weak configuration during package extraction (CWE-427) that lets an attacker-controlled element be resolved or loaded with higher privilege; exploitation requires prior local code execution but no user interaction. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires prior local low-privilege access to a Snapdragon-based device (PR:L, AV:L) - for example a malicious or compromised app or process running on the device. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H = 8.8) describes a locally-exploitable privilege escalation: the attacker must already have low-privilege code execution on the device, but the low attack complexity, absence of required user interaction, scope change, and full CIA compromise justify the High rating. … 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 described in Qualcomm's June 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/june-2026-bulletin.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Qualcomm Snapdragon-based devices across mobile, embedded, IoT, and OT fleets, record chipset and firmware versions, and open support cases with Qualcomm and device OEMs to confirm affected platforms; restrict local code execution by enforcing least privilege, application allowlisting, and disabling sideloading or developer modes on high-value devices. …
