CVE-2025-38646
MediumSummary
W jądrze systemu Linux rozwiązano podatność, która mogła prowadzić do dereferencji wskaźnika NULL podczas odbierania problematycznych pakietów na nieobsługiwanym paśmie 6 GHz. Istniało niewielkie ryzyko, że raport RX mógłby wprowadzać w błąd o odebraniu pakietu na tym paśmie, mimo że chip go nie obsługuje.
Risk Assessment
Podatność ta mogła prowadzić do nieprzewidzianych zachowań systemu, co mogłoby wpłynąć na stabilność i bezpieczeństwo komunikacji bezprzewodowej w organizacji.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe działanie funkcji związanych z obsługą sieci bezprzewodowych.

- CVE-2026-102435Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

- CVE-2026-94290Critical
The SUSE Rancher Fleet controller did not sufficiently restrict which kubeconfig secrets a Fleet Cluster object was allowed to reference. As a result, an ordinary user could define a cluster in a namespace they control and associate it with administrative credentials for the management cluster, causing the controller to manage the management cluster on that user's behalf with elevated privileges. This affects Fleet 0.16.0–0.16.3, 0.15.0–0.15.8, 0.14.0–0.14.12, 0.13.0–0.13.17 and possibly older versions.
