[Bitcoin Core Discloses High-Risk Vulnerability: TRUC Rules During Reorganization Could Cause Nodes to Failing to Produce Blocks; Fix Completed] Bitcoin Core publicly disclosed a high-risk vulnerability, CVE-2025-62861, on November 10, 2026. This vulnerability stems from the TRUC "sibling transaction eviction" logic not being restricted by `bypass_limits` during chain reorganization. This could lead to the eviction of restored transactions while leaving their descendants when transactions are re-added, resulting in inconsistent transaction pool states, miner block template creation failures, and affected nodes being unable to produce blocks before restarting. Affected versions are 28.0 to 28.2 and 29.0 to 29.1. The fix was released on October 10, 2025, in v30.0 and is retroactive to the 28.x and 29.x branches. This vulnerability was discovered and responsibly disclosed by Niklas Goegge, and Greg Sanders submitted PR 33504 to fix it.
