HIGH 7.8
DescriptionCVE.org
Memory corruption whhile handling the subsystem failure memory during the parsing of video packets received from the video firmware.
Analysis
Memory corruption whhile handling the subsystem failure memory during the parsing of video packets received from the video firmware.
Technical ContextAI
An out-of-bounds memory access occurs when code reads from or writes to memory locations outside the intended buffer boundaries. This vulnerability is classified as Out-of-bounds Write (CWE-787).
RemediationAI
A vendor patch is available — apply it immediately. Implement proper bounds checking on all array and buffer accesses. Use memory-safe languages or static analysis tools to detect OOB issues.
