PatchTheCVECVE-2024-31225: RIOT is a real-time multi-threading operating system that supports a range of devices that are typically 8-bit
CVE-2024-31225 is a high-severity flaw (CVSS 8.3) affecting riot. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
RIOT is a real-time multi-threading operating system that supports a range of devices that are typically 8-bit, 16-bit and 32-bit microcontrollers. The `_on_rd_init()` function does not implement a size check before copying data to the `_result_buf` static buffer. If an attacker can craft a long enough payload, they could cause a buffer overflow. If the unchecked input above is attacker-controlled and crosses a security boundary, the impact of th
