According to reports from Wu, Anza reported a vulnerability in the ed25519 and secp256k1 precompiled programs in the Solana Virtual Machine (SVM) affecting validator nodes running version 2.2 with the --transaction-structure view enabled. The vulnerability arose from the assumption that transaction instruction data was 2-byte aligned, leading to errors under the new transaction view with no alignment guarantees, causing discrepancies between the leader node and the bank hash within the cluster, which could result in node crashes and risks to network availability. The vulnerability was reported on April 9 by Temporal, and Anza released version 2.2.8 on April 11 to fix it by removing the alignment assumption. This vulnerability does not affect fund security. Anza recommends disabling the --transaction-structure view and upgrading to the patched version.
