Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Local driver interface requires PR:L; AC:H reflects memory-layout dependency for reliable OOB write; S:C captures cross-domain corruption potential into an adjacent security boundary.

Memory Corruption when validating input batch size and buffer plane count exceeds maximum allowed values.
AnalysisAI
Memory corruption in Qualcomm Snapdragon silicon allows a local low-privileged attacker to trigger an out-of-bounds write (CWE-787) by submitting input with a buffer plane count or batch size exceeding the maximum allowed value. The scope change in the CVSS vector (S:C) indicates the corruption can escape the vulnerable component's security boundary, yielding partial confidentiality, integrity, and availability impact on an adjacent system component. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution with at least low-privilege user access on a device running one of the affected Qualcomm Snapdragon chipsets (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.3 (Medium) with vector AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L reflects a locally-exploitable flaw requiring low privileges and high attack complexity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with low-privilege execution on a Snapdragon-powered device - such as a malicious Android application or compromised system service - submits a crafted input batch to the Qualcomm driver or firmware interface, setting a buffer plane count or batch size value beyond the validated maximum. The missing bounds check triggers an OOB write into adjacent memory, potentially corrupting data structures belonging to a neighboring security domain such as a camera subsystem, DSP, or kernel driver (consistent with the S:C scope change). … |
| Remediation | Qualcomm disclosed this vulnerability in their July 2026 Security Bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/july-2026-bulletin.html; OEMs and platform integrators should obtain updated firmware or driver packages from Qualcomm through their chipset support channels immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
