Analysis
In RRC in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 9110, W920, W930, W1000, Modem 5123, Modem 5300, and Modem 5400, the lack of a length check leads to out-of-bounds writes.
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
Implement proper bounds checking on all array and buffer accesses. Use memory-safe languages or static analysis tools to detect OOB issues.
