PatchTheCVECVE-2024-53980: RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Thi
CVE-2024-53980 is a high-severity flaw (CVSS 7.5) affecting riot. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. A malicious actor can send a IEEE 802.15.4 packet with spoofed length byte and optionally spoofed FCS, which eventually results into an endless loop on a CC2538 as receiver. Before PR #20998, the receiver would check for the location of the CRC bit using the packet length byte by considering a
