What is CVE-2023-24817?
CVE-2023-24817 is a high-severity vulnerability in RIOT-OS RIOT, published on 30 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2023.04, an attacker can send a crafted frame to the device resulting in an integer underflow and out of bounds access in the packet buffer. Triggering the access at the right time will corrupt other packets or the allocator metadata. Corrupting a pointer will lead to denial of service. This issue is fixed in version 2023.04. As a workaround, disable SRH in the network stack.
