The memory leak happens in github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey​ and ctx​. That function uses named return parameters to free pkey​ and ctx​ if there is an error initializing the context or setting the different properties. All return statements related to error cases follow the "return nil, nil, fail(...)" pattern, meaning that pkey​ and ctx​ will be nil inside the deferred function that should free them. ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Package advisory (CVE-2024-1394) Affected packages: - `github.com/golang-fips/go <= 1.22.1` - `github.com/golang-fips/openssl/v2 < 2.0.1` - `github.com/microsoft/go-crypto-openssl <= 0.2.8` - `github.com/microsoft/go-crypto-openssl/openssl < 0.2.9` Patched in: - `github.com/golang-fips/openssl/v2 2.0.1` - `github.com/microsoft/go-crypto-openssl/openssl 0.2.9` Source: https://osv.dev/vulnerability/GHSA-78hx-gp6g-7mj6
