Bitcoin Core’s Latest Bug Fixes: A New Era of ‘Minor’ Woes!

by

The good folks at Bitcoin Core have decided to grace us with four “low-severity” security advisories. How delightful! 😒

According to Michael Ford, the ever-diligent Bitcoin software maintainer, the original five issues were whittled down to four-one of them was even upgraded from “low” to “medium.” Truly, a thrilling adventure in software patching! 🎭

First up, we have the charming “CVE-2025-46598 – CPU DoS from unconfirmed transaction processing.” This delightful bug is considered so “low severity” that it only took until October 10, 2025, to fix it with Bitcoin Core v30.0. A real page-turner, this one! 📅

So, here’s the gist: A crafty attacker could send some carefully crafted unconfirmed transactions that would make a victim node sweat for just a few seconds as it validates them. These transactions would be rejected, but not before wasting a little precious time. The tragedy? Block propagation could be delayed. Oh, the horror! 😱

The second act brings us “CVE-2025-46597 – Highly unlikely remote crash on 32-bit systems.” This one’s a real treat, folks-it’s a bug that could (but probably won’t) cause a crash on 32-bit systems if the node gets a “pathological block.” Is it probable? Not at all. But let’s pretend it is for the drama. 🧟‍♂️

The Drama Continues: More Vulnerabilities, More Fixes!

And now, for the third plot twist: “CVE-2025-54604 – Disk filling from spoofed self connections.” A fabulous little bug that lets an attacker fill a victim’s disk space by pretending to be a self-connection. Exploitable? Well, it’s not exactly a fast-moving villain-this one would take a long time to cause actual harm. But the suspense, my friends, is palpable! ⏳

Finally, we have “CVE-2025-54605 – Disk filling from invalid blocks.” An absolute classic! This bug allows an attacker to cause disk space mayhem by sending a continuous stream of invalid blocks. Fear not, though-its exploitability is just as limited as the other plotlines. But do I hear a collective sigh of relief? No? Thought so. 🙄

As a final act, the Bitcoin Core team has graced us with the release of Bitcoin Core versions v29.2 and v28.3. The v27 branch? Oh, it’s now officially deceased. RIP. 🕊️
