+  An attacker could produce a block that crashes nodes running on 32-bit systems in a rare edge case. A fix was released on October 10th 2025 in Bitcoin Core v30.0.
+---
+
+Disclosure of the details of a bug on 32-bit systems which may, in a rare edge case, cause the node
+to crash when receiving a pathological block. This bug would be extremely hard to exploit. A fix was
+released on October 10th 2025 in Bitcoin Core v30.0.
+
+This issue is considered **Low** severity.
+
+## Details
+
+Before writing a block to disk, Bitcoin Core checks that its size is within a normal range. This
+check would overflow on 32-bit systems for blocks over 1GB, and make the node crash when writing it
+to disk. Such a block cannot be sent using the `BLOCK` message, but could in theory be sent as a
+compact block if the victim node has a non-default large mempool which already contains 1GB of
+transactions. This would require the victim to have set their `-maxmempool` option to a value
+greater than 3GB, while 32-bit systems may have at most 4GiB of memory.
+
+This issue was indirectly prevented by capping the maximum value of the `-maxmempool` setting on
+32-bit systems.

+
+Disclosure of the details of a resource exhaustion issue when processing an unconfirmed transaction.
+A fix was released on October 10th 2025 in Bitcoin Core v30.0.
+
+This issue is considered **Low** severity.
+
+## Details
+
+An attacker could send specially-crafted unconfirmed transactions that would take a victim node a
+few seconds each to validate. The non-standard transactions would be rejected but not lead to a
+disconnection and the process could be repeated. This could be exploited to delay block propagation.
+
+The issue was mitigated in multiple steps by reducing the validation time in different Script
+contexts.

+
+Pieter Wuille, Anthony Towns and Antoine Poinsot implemented mitigations to reduce the worst case
+validation time of unconfirmed transactions.

+  An attacker could cause a victim node to fill up its disk space by repeatedly faking self-connections over a long time. A fix was released on October 10th 2025 in Bitcoin Core v30.0.
+---
+
+Disclosure of the details of a log-filling bug which allowed an attacker to fill up the disk space
+of a victim node by faking self-connections. Exploitability of this bug is limited, and it would
+take a long time before it would cause the victim to run out of disk space.  A fix was released on
+October 10th 2025 in Bitcoin Core v30.0.
+
+This issue is considered **Low** severity.
+
+## Details
+
+Bitcoin Core would unconditionally log in case of self-connection. This could be exploited by an
+attacker by waiting for a victim to connect to it and reusing the version message nonce to establish
+many connections to the victim, causing it to detect those attempts as self-connections. However,
+exploitability is limited because the initial connection from the victim will timeout after 60
+seconds by default.
+
+This issue was fixed by implementing log rate-limiting across the board, also preventing future
+issues of the same type from happening.

+Eugene Siegel and Niklas Goegge worked on a fix mitigating all types of log-filling attacks.
