The V12 security team has released a working PoC for PinTheft, a Linux kernel local privilege escalation tied to a double-free in the RDS (Reliable Datagram Sockets) zerocopy send path that can be turned into a page-cache overwrite through io_uring fixed buffers. The bug was patched earlier in May but has no assigned CVE yet. Exploitation requires the RDS module to be loaded - default only on Arch Linux among the major distributions - plus io_uring enabled and a readable SUID-root binary. PinTheft joins DirtyDecrypt, Dirty Frag, Fragnesia, and Copy Fail in a recent run of Linux LPE disclosures.
Microsoft has assigned CVE-2026-45585 and shipped mitigation guidance for YellowKey, a Windows BitLocker bypass that anonymous researcher 'Nightmare Eclipse' disclosed last week with a working PoC. The attack places crafted FsTx files on a USB drive or EFI partition, reboots into WinRE, and holds CTRL during boot to drop into a shell with full access to BitLocker-protected drives. Microsoft says no patch is available yet. Mitigations include removing the autofstx.exe entry from Session Manager's BootExecute and reconfiguring BitLocker to require TPM+PIN at startup. Nightmare Eclipse is the same researcher who recently dropped BlueHammer, RedSun, GreenPlasma, UnDefend, and MiniPlasma.
ReliaQuest has documented active in-the-wild exploitation of CVE-2024-12802, a SonicWall Gen6 SSL-VPN MFA bypass that hits Gen6 devices even after they apply the firmware patch. SonicWall's advisory makes clear that on Gen6 hardware, the firmware update alone does not fix it - administrators must also delete the LDAP configuration that uses userPrincipalName, remove cached LDAP users, drop the SSL VPN User Domain back to LocalDomain, reboot, and rebuild the LDAP config without userPrincipalName. Gen7 and Gen8 devices are patched by firmware alone. Intrusions observed between February and March 2026 looked like ransomware initial-access broker activity with 30-60 minute Cobalt Strike and BYOVD attempts.
Drupal has shipped the highly critical core security release teased by PSA-2026-05-18. The flaw lets attackers achieve remote code execution on Drupal sites running PostgreSQL backends. Fixed versions are 11.3.10, 11.2.12, 11.1.10, 10.6.9, 10.5.10, and 10.4.10. The releases for supported branches also pull in upstream Symfony and Twig security fixes, making the upgrade essential even on MySQL deployments. Best-effort manual patches are available for end-of-life Drupal 9.5 and 8.9. Drupal 7 is not affected. The Drupal Security Team had warned that working exploits could follow within hours of disclosure, so administrators should patch now.
HiddenLayer has disclosed a maximum-severity unauthenticated remote-code-execution vulnerability, CVE-2026-45829, in ChromaDB's Python FastAPI server. ChromaDB is one of the most popular vector databases backing retrieval-augmented-generation pipelines, with about 14 million monthly PyPI downloads. A vulnerable endpoint marked as authenticated lets an attacker embed model settings before authentication is checked, so a crafted request makes ChromaDB load a malicious model from Hugging Face and execute it locally. The auth check fires only after the payload has already run. The bug was introduced in 1.0.0 and was still present in 1.5.8. HiddenLayer's Shodan sweep shows ~73% of internet-exposed Chroma instances are vulnerable.
Drupal is releasing an emergency core security update on May 20 between 17:00 and 21:00 UTC. Pre-disclosure advisory PSA-2026-05-18 rates the issue 'highly critical' (20 of 25 on Drupal's scoring) and notes access complexity 'None' and authentication 'None' - meaning the underlying flaw is unauthenticated and easy to trigger. Patches will land for the supported 11.3.x, 11.2.x, 10.6.x, and 10.5.x branches, plus emergency patches for EOL 11.1.x and 10.4.x. Drupal 7 is not affected. Drupal 8 and 9 will only get best-effort manual patch files. The Drupal Security Team warns working exploits may follow within hours of disclosure.
Researchers have disclosed a chain of vulnerabilities in SEPPmail Secure Email Gateway that lets an attacker turn unauthenticated web requests into remote code execution by inflating the SEPPMaillog file past its 10,000 KB limit, which forces newsyslog to rotate logs and signal syslogd to reload its configuration. Combined with the other flaws in the chain, the attacker reads all mail traffic on the appliance and persists indefinitely. SEPPmail has patched CVE-2026-44128 in version 15.0.2.1, CVE-2026-44126 in 15.0.3, and the rest in 15.0.4. The disclosure follows last month's CVE-2026-27441 (CVSS 9.5) OS command-execution fix in the same appliance.
Recorded Future News has connected last summer's three-hour POST Luxembourg outage - which took down landline, 4G, and 5G networks across the country and left residents unable to dial emergency services - to a zero-day in Huawei enterprise routers running VRP. Specially crafted network traffic merely passing through caused the routers to enter a continuous restart loop. Luxembourg's prosecutor concluded no one had targeted Luxembourg specifically; the data was just transit traffic. Huawei has not assigned a CVE for the bug and routes its enterprise advisories through a restricted customer portal rather than publicly, leaving operators with little ability to track exposure.
A working proof-of-concept exploit for a recently patched Linux kernel local privilege escalation is now public. Researchers at V12 found the bug in May and were told it had already been fixed in the mainline kernel on April 25, matching CVE-2026-31635 per Tharros analyst Will Dormann. The flaw is a missing copy-on-write check in rxgk_decrypt_skb, the kernel routine that decrypts RxGK packets for the Andrew File System. Exploitation requires CONFIG_RXGK, limiting impact to leading-edge distros like Fedora, Arch Linux, and openSUSE Tumbleweed. DirtyDecrypt joins Dirty Frag, Fragnesia, and Copy Fail in a recent wave of Linux LPE disclosures.
Researchers at Cyera have disclosed a chain of four vulnerabilities in OpenClaw, an open-source autonomous AI agent platform that Nvidia and Tencent have built enterprise products on top of. The chain - CVE-2026-44112 (CVSS 9.6), CVE-2026-44113, CVE-2026-44115, and CVE-2026-44118 - lets an attacker who can influence the agent's input (through a malicious plugin, prompt injection, or compromised tool output) break out of the OpenShell sandbox, read environment-stored API keys, elevate to owner-level privileges, and write persistent backdoors. Each step looks like normal agent behavior. Shodan and Zoomeye between them counted 65,000 to 180,000 public OpenClaw instances earlier in May. All flaws are fixed in OpenClaw 2026.4.22.
