Heap-based buffer overflow in JPEG decoder of libimagecodec.quram.so prior to SMR Sep-2026 Release 1 allows remote attackers to execute arbitrary code.
AnalysisAI
Remote code execution in Samsung Mobile Devices arises from a heap-based buffer overflow in the JPEG decoding path of libimagecodec.quram.so (the proprietary Quram/Qmage image codec) on builds prior to SMR Sep-2026 Release 1. A remote attacker who delivers a maliciously crafted JPEG image to a vulnerable device can corrupt heap memory and execute arbitrary code in the context of the image-processing component. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target device to decode an attacker-supplied JPEG using the vulnerable libimagecodec.quram.so on a Samsung firmware build prior to SMR Sep-2026 Release 1 (Android 14/15/16/17). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The Samsung CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H) describes an unauthenticated, network-reachable, no-user-interaction memory-corruption bug with full confidentiality, integrity, and availability impact on the vulnerable system - a genuinely high-priority profile for a consumer device fleet of this scale. … 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-released patch: install SMR Sep-2026 Release 1 (or later) for the applicable Android 14/15/16/17 base via Settings > Software update, as published in Samsung's September 2026 security bulletin (https://security.samsungmobile.com/securityUpdate.smsb?year=2026&month=09). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, issue urgent guidance to all users to disable image preview and auto-loading features in messaging and email applications and to avoid opening JPEG images from untrusted sources. …
