Last modified
CVE-2022-37454 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 5.19% chance of exploitation in the next 30 days.
