After Bitcoin Core 0.14.0 and before Bitcoin Core 29.0, validating a specially-crafted block may cause the node to access previously freed memory.
During validation, necessary data required for checking inputs for each transaction is pre-calculated and cached. For specially crafted invalid blocks, it was possible for this data to be destroyed while it was still being accessed by a background validation thread. An attacker capable of mining a block with sufficient proof-of-work could have exploited this to crash victim nodes. Because of the nature of use-after-free bugs, it is possible that the crash could have been used for remote code execution, though constraints on the input (block) data make this unlikely.
This issue is considered High severity.

Details
By default, script validation for new blocks is dispatched to background threads via a vector of CScriptCheck functors. Each CScriptCheck holds a pointer to a PrecomputedTransactionData object which stores some data needed by each input in the transaction. Because it stores a pointer and not the data itself, care must be taken to ensure that the PrecomputedTransactionData outlives the CScriptCheck.
The script checks lifetime is enforced by an RAII class, CCheckQueueControl. However, the control is intantiated before the precomputed transaction data. Because local objects in C++ are destructed in reverse order of construction, this means the vector of PrecomputedTransactionData is destroyed before the CCheckQueueControl.
This is not an issue when the block is valid, as CCheckQueueControl::Wait() will be called before the function returns and the PrecomputedTransactionData gets destroyed. However, in case of an early return (when a separate check fails) a background script thread may read the precomputed transaction data after it was destroyed. An attacker could exploit this to crash victim nodes at the expense of a valid PoW at tip.

[CVE-2025-62514] [Modified: 02-03-2026] [Analyzed] [V3.1 S8.3:HIGH] Parsec is a cloud-based application for cryptographically secure file sharing. In versions on the 3.x branch prior to 3.6.0, `libparsec_crypto`, a component of the Parsec application, does not check for weak order point of Curve25519 when compiled with its RustCrypto backend. In practice this means an attacker in a man-in-the-middle position would be able to provide weak order points to both parties in the Diffie-Hellman exchange, resulting in a high probability to for both parties to obtain the same shared key (hence leading to a successful SAS code exchange, misleading both parties into thinking no MITM has occurred) which is also known by the attacker. Note only Parsec web is impacted (as Parsec desktop uses `libparsec_crypto` with the libsodium backend). Version 3.6.0 of Parsec patches the issue.
