NCSC Warns of Critical Check Point VPN Flaws as Large-Scale Exploitation Is Expected

Dutch NCSC warns of two critical CVSS 9.8 Check Point VPN flaws enabling unauthenticated remote code execution, urging immediate patching before mass exploitation.

The Dutch NCSC warned that CVE-2026-85102 and CVE-2026-85103, both rated 9.8 CVSS, allow unauthenticated remote attackers to execute arbitrary code on Check Point Quantum Security Gateway, Spark Firewall, and Security Management Server deployments when VPN is enabled. CVE-2026-85102 stems from improper certificate trust validation during VPN negotiation, while CVE-2026-85103 is a heap-based buffer overflow in ASN.1 certificate decoding. Check Point shipped emergency updates on September 9, 2026, including R82.10 Take 44, R82 Take 126, and R81.20 Take 166 or later, plus LivePatch for eligible systems. No public exploit code exists yet, but the NCSC rates exploitation likelihood high and recommends restricting UDP ports 500 and 4500 to known peers as a stopgap.

New ZcopyReaper Linux Kernel Vulnerability Enables Privilege Escalation Attacks

ZcopyReaper (CVE-2026-43502) lets unprivileged local attackers reach root on Linux via an RDS zero-copy cleanup flaw dating to kernel 4.17.

CVE-2026-43502 is a lifetime-management error in rds_message_purge() that mishandles zero-copy sends before socket attachment, corrupting kernel memory and enabling local privilege escalation without capabilities or user namespaces. NebuSec demonstrated the exploit on openSUSE kernel 6.4.0-150600.23.100; vulnerable systems need CONFIG_INET, CONFIG_AIO, CONFIG_RDS, and CONFIG_RDS_TCP. The fix landed in mainline commit 44b550d88b26 (Linux 7.1-rc3) with backports to Ubuntu 7.0.0, 6.8.0, and 5.15.0 kernels and multiple Debian branches. NebuSec also released public exploits for 20 additional Linux kernel vulnerabilities in its CyberMeowfia repository.

VU#212479: Sentry Seer vulnerability allows attacker-controlled input to be executed in a privileged environment

CERT/CC details CVE-2026-90999: attacker-controlled Sentry telemetry can steer the Seer coding agent into executing attacker code with repository access.

CERT/CC published VU#212479 for CVE-2026-90999 in Sentry Seer: attacker-submitted events through public DSN endpoints flow into Seer's root-cause analysis, which is embedded directly into the coding agent's initial prompt. In the documented chain, the privileged coding agent downloads and executes an attacker-controlled package before any human review, yielding arbitrary code execution with access to connected source repositories. No vendor patch is available yet; mitigations include disabling automated remediation, restricting coding-agent package installation, and filtering telemetry before Seer analysis.

AWS Systems Manager Agent Vulnerability Allows Attackers to Bypass Port-Forwarding Restrictions

Critical SSRF flaw in AWS SSM Agent (CVE-2026-89049) lets authenticated users bypass link-local denylists and reach EC2 Instance Metadata Service for IAM credentials.

CVE-2026-89049 (Critical, CVSS v3.1 AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) affects Amazon SSM Agent versions earlier than 3.3.4851.0, with the fix shipping in 3.3.4851.0.

VU#369093: MLflow dspy and statsmodels flavors bypass pickle deserialization control

CERT/CC warns MLflow's dspy and statsmodels flavors bypass the MLFLOW_ALLOW_PICKLE_DESERIALIZATION control, enabling remote code execution.

CERT/CC vulnerability note VU#369093 describes a flaw in MLflow 3.12.0 where the dspy flavor conditionally applies the pickle deserialization safety control based only on the model path's .pkl extension, while the statsmodels flavor skips the check entirely, permitting arbitrary code execution via malicious pickle payloads even when users disallow pickle. The statsmodels flavor is patched in versions 3.15.0 and later, but no dspy fix exists yet, so users should avoid loading models through that flavor. Exploitation requires write access to any location from which a user obtains MLflow models.

Telegram Desktop Flaw Lets Hidden JavaScript Exfiltrate Messages From HTML Exports

Telegram Desktop HTML export XSS (CVSS 8.2) let bot messages exfiltrate exported chats; fixed in 7.0.1 but old exports stay vulnerable.

ExPatch researchers found that Telegram Desktop versions 4.15.1 (March 2024) through 6.9.3 wrote bot inline-keyboard button text into HTML chat exports without escaping, allowing a bot to plant invisible JavaScript. When a user opened the export in a browser, the script could exfiltrate every message in that 1,000-message file, rewrite the displayed content, or fake a verification form. The flaw (rated CVSS 3.1 8.2) was fixed by commit 8457d13a in 6.9.4 beta (July 3, 2026) and 7.0.1 stable (July 14, 2026), but pre-fix exports remain dangerous since updating the app does not fix old files. No CVE identifier or Telegram security advisory exists, and no exploitation in the wild is claimed.

ZDI-26-695: Linux Kernel NFSv4 server race condition (CVE-2026-89688, CVSS 8.5) enables remote code execution on nfsd systems with authentication.

ZDI advisory ZDI-26-695 describes a race condition in the Linux Kernel NFSv4 server tracked as CVE-2026-89688 with a CVSS score of 8.5. Remote attackers can execute arbitrary code, but authentication is required and only systems with nfsd enabled are vulnerable. No in-the-wild exploitation is mentioned in the advisory.

ZDI-26-694: Linux Kernel Net Scheduler Clsact Qdisc Use-After-Free Local Privilege Escalation Vulnerability

ZDI discloses CVE-2026-23413, a use-after-free in the Linux kernel net scheduler clsact qdisc allowing local privilege escalation, CVSS 8.2.

ZDI advisory ZDI-26-694 describes a use-after-free vulnerability in the Linux kernel's net scheduler clsact qdisc component. Successful exploitation allows local attackers to escalate privileges on affected installations, and ZDI assigned a CVSS score of 8.2. The flaw is tracked as CVE-2026-23413. The advisory notes an attacker must first obtain the ability to execute high-privileged code on the target system to exploit the vulnerability.

ZDI-26-697: Linux Kernel NTFS3 Out-Of-Bounds Read Information Disclosure Vulnerability

ZDI-26-697: Linux Kernel NTFS3 out-of-bounds read rated CVSS 7.3 lets local low-privileged attackers disclose sensitive information.

ZDI advisory ZDI-26-697 describes an out-of-bounds read in the Linux Kernel NTFS3 driver rated CVSS 7.3. An attacker must first be able to execute low-privileged code on the target system to exploit the flaw. Successful exploitation leads to sensitive information disclosure. No CVE identifier is listed in the advisory.

ZDI-26-680: Linux Kernel Crypto Subsystem Use-After-Free Local Privilege Escalation Vulnerability

ZDI discloses a Linux kernel crypto subsystem use-after-free (CVE-2026-31719, CVSS 8.8) letting local low-privileged attackers escalate to root.

ZDI advisory ZDI-26-680 covers a use-after-free vulnerability in the Linux kernel crypto subsystem, tracked as CVE-2026-31719 with a CVSS score of 8.8. A local attacker who can already execute low-privileged code can exploit it to escalate privileges on affected installations. The advisory does not report any exploitation in the wild.
