CVE-2026-23068
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z podwójnym zwolnieniem pamięci w ścieżce błędu podczas próby rejestracji kontrolera SPI. Problem występował w sterowniku spi-sprd-adi, który używał spi_alloc_host() do alokacji kontrolera, ale rejestrował go za pomocą devm_spi_register_controller().
Risk Assessment
Podwójne zwolnienie pamięci może prowadzić do nieprzewidywalnych zachowań systemu, w tym do awarii lub potencjalnego zdalnego wykonania kodu. Organizacje powinny być świadome ryzyka związanego z używaniem podatnych wersji jądra.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia ewentualnych nieprawidłowości.

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.
