CVE-2026-40012

The vulnerability CVE-2026-40012 affects configurations with ECS enabled, where ECS zero-scoped answers are stored in the packet cache instead of being properly restricted, potentially leaking to clients. The issue has a network-based attack surface with low confidentiality impact (CVSS v3.1: 5.3...

CVE-2026-53241

CVE-2026-53241 concerns the Linux kernel ALSA: seq (dummy) port handling of UMP events. The issue arises when a UMP event is copied into a stack temporary and then dispatched; the temporary storage is legacy-sized, while the UMP packet is larger, leading to a read past the end of the temporary. T...
