The Bitcoin Core project disclosed a vulnerability that could freeze miner nodes. A fix was released with the October 2025 version.
Details were withheld until the last vulnerable release line, 29.x, reached end of support on October 27. After that, unupgraded nodes would no longer receive patches.
· Disclosure was tied to the end of the 29.x lifecycle, leaving miner nodes running that release line outside the scope of the fix.
· The source material does not explain the conditions that trigger the vulnerability or the proportion of nodes affected.
Are you running version 29.x, or have you upgraded?
