CVE-2025-38307
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z ASoC: Intel: avs, polegającą na braku weryfikacji zawartości zwracanej przez funkcję parse_int_array(). Pierwszy element zwracanego tablicy przechowuje swoją długość, a jeśli wynosi ona 0, wszelkie manipulacje poza elementem o indeksie 0 kończą się dereferencją wskaźnika null.
Risk Assessment
Podatność ta może prowadzić do awarii systemu lub nieprzewidzianego zachowania aplikacji, co stwarza ryzyko dla stabilności i bezpieczeństwa systemu operacyjnego. W przypadku wykorzystania tej luki, atakujący może uzyskać dostęp do krytycznych zasobów systemowych.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, w której ta podatność została załatana. Należy również monitorować systemy pod kątem nieautoryzowanych zmian i potencjalnych exploitów.

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.

Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Verify content returned by parse_int_array() The first element of the returned array stores its length. If it is 0, any manipulation beyond the element at index 0 ends with null-ptr-deref.
