AC:H reflects 32-bit platform requirement and application-specific image ingestion path; no confidentiality impact from stride miscalculation alone.

Lifecycle Timeline
1DescriptionCVE.org
A weakness has been identified in embedded-graphics up to 0.8.2 on 32-bit. Impacted is the function ImageRaw::new/bytes_per_row of the file src/image/image_raw.rs. This manipulation causes integer overflow. The attack is possible to be carried out remotely. Upgrading the affected component is recommended. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Integer overflow in the embedded-graphics Rust library (versions through 0.8.2) affects the bytes_per_row calculation inside ImageRaw::new on 32-bit compilation targets, causing incorrect buffer stride values that can lead to out-of-bounds memory access when processing crafted image data. The flaw was disclosed through GitHub issue #820, but the project had not responded with a fix at time of reporting. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following: (1) the target application is compiled for a 32-bit architecture where usize is 32 bits wide (e.g., ARM Cortex-M, ESP32 in 32-bit mode, RISC-V RV32) - 64-bit targets are entirely unaffected; (2) the application uses the ImageRaw::new API with image dimensions that are at least partially attacker-controlled; (3) the attacker can deliver image data to the device through any channel the application exposes (network socket, Bluetooth, serial interface, file). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) scores 6.9 and characterizes the flaw as unauthenticated remote-network exploitable with low complexity, but several factors constrain real-world risk well below that framing. … 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 has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
