Last modified Jun 17, 2026

CVE-2022-23218 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.. EPSS estimates a 4.73% chance of exploitation in the next 30 days.
