New Linux ‘Copy Fail’ flaw gives hackers root on major distros
An exploit has been published for a local privilege escalation vulnerability dubbed “Copy Fail” that impacts Linux kernels released since 2017, allowing an unprivileged local attacker to gain root permissions.
The vulnerability is tracked as CVE-2026–31431 and was discovered by the offensive security company Theori, using its AI-driven pentesting platform Xint Code after scaning the Linux crypto/ sybsystem for about an hour.
Theori reported the finding to the Linux kernel security team on March 23, and patches became available within a week. Technical details and a proof-of-concept exploit for the flaw emerged publicly yesterday.
CISA orders feds to patch Windows flaw exploited as zero-day
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to secure their Windows systems against a vulnerability exploited in zero-day attacks.
Tracked as CVE-2026–32202, this security flaw was reported by cybersecurity firm Akamai, which described it as a zero-click NTLM hash leak vulnerability left behind after Microsoft incompletely patched a remote code execution flaw (CVE-2026–21510) in February.
As CERT-UA revealed, the Russian APT28 (aka UAC-0001 and Fancy Bear) cyberespionage group exploited CVE-2026–21510 in attacks against Ukraine and EU countries in December 2025 as part of an exploit chain that also targeted a LNK file flaw (CVE-2026–21513).
The Fermi Paradox Just Got Worse

The Fermi Paradox is the question of why we haven’t been contacted by any extraterrestrial species. In a recent paper, astrophysicists analyzed the paradox by instead examining how civilizations with the ability to send signals through space might develop. Unfortunately for us, their findings are quite bleak – but let’s take a look anyway.
