Memory Corruption when parsing jpeg commands due to unaccounted extra writes to the buffer during validation checks.
AnalysisAI
Out-of-bounds write in Qualcomm Snapdragon's JPEG command parser exposes local low-privilege users to memory corruption via crafted JPEG input. Validation checks within the parser fail to account for extra buffer writes, overwriting adjacent memory and enabling a scope change beyond the vulnerable component's boundary - consistent with Snapdragon's isolated subsystem architecture (DSP, camera ISP). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local access to the target Snapdragon-based device with at least low-privilege execution (PR:L) - a locally installed application or shell session suffices; no network path exists (AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS rates this 5.3 Medium with AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with a low-privilege application on a Snapdragon-powered Android device crafts a malicious JPEG payload designed to trigger the off-by-more write during validation. By invoking a camera HAL or media codec interface that routes input to the vulnerable Snapdragon JPEG parser, the attacker causes out-of-bounds memory writes that corrupt adjacent memory in a neighboring subsystem component. … |
| Remediation | Apply the security update published in the Qualcomm July 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/july-2026-bulletin.html); the bulletin contains chipset-specific patch details. … Detailed patch versions, workarounds, and compensating controls in full report. |
