CVE-2023-24817
30.05.2023, 16:15
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.

Common Weakness Enumeration
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory BufferThe software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.
- CWE-191 - Integer Underflow (Wrap or Wraparound)The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
