Information Disclosure when a pointer is reused after being deallocated.

AnalysisAI

Local information disclosure in Qualcomm Snapdragon chipsets allows a low-privileged process to read freed memory from a higher trust boundary, potentially leaking sensitive data. The vulnerability requires local access and low privileges (CVSS 7.3, AV:L/PR:L), with no user interaction or network vector. …

Vulnerability AssessmentAI

Exploitation Requires local access with low privileges (a running low-privileged process/app) on an affected Qualcomm Snapdragon device - no user interaction and no network path. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L, base 7.3) describes a locally-exploitable, low-privilege information-disclosure flaw with a scope change and high confidentiality impact - consistent with a low-privileged process reading freed kernel/driver memory that belongs to a higher trust boundary. … 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 Vendor-released patch: consult the Qualcomm September 2026 security bulletin for per-SoC patches. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory the estate against the Qualcomm September 2026 security bulletin to identify which Snapdragon SKUs and software builds we actually operate, and open a tracking record with each device OEM and our mobile device management and Windows-on-Arm procurement contacts to confirm their remediation timelines, since no vendor-released patch exists for CVE-2026-25284 today. …
