Bitcoin Core discloses three patched flaws, one high-severity mining bug

Bitcoin Core developers disclosed three security flaws that were already patched, including one that could stop some nodes from building new blocks. The bug was fixed over a year ago, but older nodes may still be exposed.

Bitcoin Core developers have made public three security vulnerabilities that had already been patched. The most serious is rated high-severity and could stop affected nodes from building new blocks, which would keep miners from producing new Bitcoin blocks.

The problem appeared during chain reorganizations, when a node swaps out recent blocks it had accepted for a different version of the chain. In those cases, the node's mempool, the pool of unconfirmed transactions waiting to be added to a block, could become corrupted.

Developers fixed the problem more than a year ago. Nodes that still run older software may remain at risk, so the fix matters most to operators who have updated their software.
