CVE-2007-6694
HighSummary
Funkcja chrp_show_cpuinfo w jądrze Linux od wersji 2.4.21 do 2.6.18-53 na architekturze PowerPC może umożliwić lokalnym użytkownikom spowodowanie awarii systemu. Problem ten występuje w wyniku nieznanych wektorów, które powodują niepowodzenie funkcji of_get_property, co prowadzi do dereferencji wskaźnika NULL.
Risk Assessment
Podatność ta może prowadzić do awarii systemu, co skutkuje przerwaniem dostępności usług. Może to wpłynąć na stabilność i ciągłość działania systemów korzystających z podatnej wersji jądra.
Recommendation
Zaleca się aktualizację jądra Linux do wersji, która nie jest podatna na tę lukę. Należy również monitorować systemy pod kątem nieautoryzowanych działań lokalnych użytkowników.

An authenticated attacker with client management permissions can bypass security controls and upload a malicious JavaScript policy that executes on the server.
- CVE-2026-122041Critical
The Checkout Field Editor for WooCommerce (Pro) plugin for WordPress up to and including 3.8.0 is vulnerable to unauthorized deletion of arbitrary attachments due to a missing capability/ownership check in the ajax_remove_uploaded() function. The handler is registered for both wp_ajax and wp_ajax_nopriv and gated solely by the 'file_handling_nonce' nonce, which is exposed in the public checkout page markup.
- CVE-2026-119075Critical
The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in FormHandler::validate_checkout_fields() in versions up to and including 1.1.4. The checkout registration path stores the raw $_POST['user_roles'] value without validation, and add_user_data() injects it as the new account's role.
- CVE-2026-118066Critical
The LatePoint plugin for WordPress is vulnerable to authentication bypass via account takeover in versions up to and including 5.7.6. OsModel::build_conditions_query() compares WHERE-clause values against literal strings 'IS NULL' and 'IS NOT NULL' and concatenates a match directly into SQL without binding, allowing unauthenticated attackers to send params[password_reset_token]=IS NOT NULL to the public customer_cabinet__change_password AJAX route and overwrite the lowest-id customer's password.
- CVE-2026-104014Critical
The Naimur Email OTP Verification for WooCommerce plugin is vulnerable to authentication bypass in versions up to and including 2.1.0. The password-reset finalization endpoint authorizes the reset solely by the presence of a database row marking an email as 'VERIFIED', with no timestamp check, session binding, or per-reset token, and the scheduled cleanup cron has no handler so it never runs.
Original NVD description (English source)
The chrp_show_cpuinfo function (chrp/setup.c) in Linux kernel 2.4.21 through 2.6.18-53, when running on PowerPC, might allow local users to cause a denial of service (crash) via unknown vectors that cause the of_get_property function to fail, which triggers a NULL pointer dereference.
