CVE-2025-38403
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z niewłaściwym inicjowaniem pakietu transportowego vmci. Funkcja vmci_transport_packet_init nieczyściła poprawnie pakietu, co mogło prowadzić do pozostawienia niezinicjowanych danych w strukturze.
Risk Assessment
Niewłaściwe inicjowanie pakietów może prowadzić do nieprzewidywalnych zachowań systemu oraz potencjalnych luk w zabezpieczeniach, które mogą być wykorzystane przez atakujących.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe inicjowanie pakietów transportowych.

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.

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.
