CVE-2026-64389

Summary: CVE-2026-64389 affects the Linux kernel KSMD (ksmbd) SMB3 multichannel binding path. The code derives the NTLMv2 session key into sess->sess_key during ksmbd_auth_ntlmv2(), before validating the NTLMv2 response. If authentication fails, the subsequent KEY_XCH step may still use the (p...

Isolated but Exposed: Persistence-Based Memory Extraction Attack on LLM Agents

LLM-based agents extend large language models with long-term memory LTM that persists privacy-sensitive user data across sessions. Production systems mitigate extraction risks through memory isolation, binding each user's LTM to a unique identifier. This defense has blocked known attacks on share...
