according to The Block, the official Ethereum client Geth (go-ethereum) development team issued an emergency announcement on February 18, requiring validators using version v1.15.1 to upgrade immediately to version v1.15.2. This update aims to prevent network stability issues and validator operation interruptions.

The development team pointed out that version v1.15.1 has a regression issue that may cause block creation failures on the Ethereum mainnet, causing validators to miss out on block creation opportunities, resulting in loss of block rewards and transaction fees.

It is reported that Geth is the most widely used execution layer client for Ethereum, with over 40% of validators using the software. This update follows a patch that fixed a vulnerability that could potentially lead to nodes being vulnerable to denial of service attacks.
