Network vector applies only if device exposes image ingestion; AC:H because exploitation requires crafted width reaching draw_sub_image via untrusted path, a non-default deployment condition.

Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was determined in embedded-graphics up to 0.8.2. This affects the function ImageRaw::draw_sub_image of the file src/image/image_raw.rs. Executing a manipulation of the argument width can lead to integer overflow. The attack may be launched remotely. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Integer overflow in embedded-graphics ≤0.8.2 allows remote attackers to trigger memory corruption or denial-of-service by supplying a crafted width argument to ImageRaw::draw_sub_image in src/image/image_raw.rs. Rust's release-mode silent integer wraparound means the overflow propagates into buffer size calculations or slice indexing, potentially causing out-of-bounds memory access on the target embedded device. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target application must use embedded-graphics ≤0.8.2 and invoke `ImageRaw::draw_sub_image` with a width value derived from untrusted external input (e.g., image metadata received over a network interface, BLE, serial, or other communication channel). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N, score 6.9) assumes fully network-accessible exploitation with no prerequisites, which may overstate real-world risk. … 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 | No vendor-released patch identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
