This week

HIGH 7.5REMOTEDOWNGRADE

CVE-2025-58157 is a high-severity flaw (CVSS 7.5) affecting gnark. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

gnark is a zero-knowledge proof system framework. In version 0.12.0, there is a potential denial of service vulnerability when computing scalar multiplication is using the fake-GLV algorithm. This is because the algorithm didn't converge quickly enough for some of the inputs. This issue has been patched in version 0.13.0.

consensys gnark DOWNGRADE

Affected: 0.12.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.12.0

1. Check installed version

apt-cache policy gnark || rpm -q gnark || gnark --version

2. No fixed release: DOWNGRADE to a release before 0.12.0 (Debian / Ubuntu)

apt-cache madison gnark sudo apt install gnark=<VERSION_BEFORE_0.12.0> sudo apt-mark hold gnark

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gnark sudo dnf downgrade gnark-<VERSION_BEFORE_0.12.0> sudo dnf versionlock add gnark

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
