Spring AI: ChatMemory DEFAULT_CONVERSATION_ID causes unintended cross-user data leakage

Spring AI's chat memory component contained a problematic default that, when not explicitly overridden, could result in unintended data exposure between users...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...
