CVE-2022-37454
CWE-190Published: October 21, 2022· Updated: Jun 17, 2026
Official Description
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface.
Risk Analysis
An integer overflow in the Keccak XKCP SHA-3 reference implementation can lead to a buffer overflow, potentially allowing arbitrary code execution. Given the widespread use of this cryptographic library, the critical 9.8 CVSS score reflects a significant risk to affected systems.
There is no known public exploit for this vulnerability, and it is not in the CISA KEV. It is remotely exploitable with low attack complexity.
Update the Keccak code package to the latest version and apply patches provided by Linux distributions like Debian and Fedora.
Technical Analysis
CVE-2022-37454 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
