CVE-2022-24921 is an uncontrolled resource-consumption vulnerability in Go's regexp package. In Go releases before 1.16.15 and Go 1.17 releases before 1.17.8, regexp.Compile can recursively process a sufficiently deeply nested regular expression until stack resources are exhausted. An application that compiles attacker-controlled regular expressions can consequently crash the Go runtime.
