Local low-priv app supplies unvalidated offset/length for an OOB write with no user interaction; memory corruption gives full C/I/A within the same component, so scope unchanged.

Lifecycle Timeline
3DescriptionCVE.org
Memory Corruption when processing data with large offset and length values exceeds buffer limits during data copy operations.
AnalysisAI
Local privilege escalation on Qualcomm Snapdragon devices is possible via an out-of-bounds write (CWE-787) in data-copy operations that fail to validate large offset and length values. An attacker with low privileges already executing code on the device-such as an unprivileged application-can trigger memory corruption to achieve high confidentiality, integrity, and availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local access with low privileges on an affected Qualcomm Snapdragon device (AV:L/PR:L) - the attacker must already be able to execute code, e.g. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, 7.8 HIGH) is internally consistent and credible: this is a local, low-complexity, low-privilege out-of-bounds write (CWE-787) yielding full C/I/A impact - classic memory-corruption escalation-of-privilege territory. … 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 vendor patch as detailed in the Qualcomm September 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html); the bulletin provides the specific patched versions for each affected Snapdragon chipset. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Qualcomm Snapdragon-based devices (Android smartphones, tablets, and embedded systems) and confirm exposure to CVE-2026-24074; review the September 2026 Qualcomm security bulletin and OEM advisories for updated patch guidance; No vendor-released patch identified at time of analysis. …
