CVE-2025-38190
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z funkcją atm_account_tx(). W przypadku niepowodzenia funkcji copy_from_iter_full(), następuje wycofanie operacji w atm_account_tx().
Risk Assessment
Podatność ta może prowadzić do nieprawidłowego zarządzania pamięcią, co w konsekwencji może wpłynąć na stabilność systemu oraz bezpieczeństwo danych.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz zapewnić prawidłowe zarządzanie pamięcią.

In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.

In the Linux kernel, the following vulnerability has been resolved: atm: Revert atm_account_tx() if copy_from_iter_full() fails. In vcc_sendmsg(), we account skb->truesize to sk->sk_wmem_alloc by atm_account_tx(). It is expected to be reverted by atm_pop_raw() later called by vcc->dev->ops->send(
