Linux 6.9 LUKS Suspend Bug Leaves Encryption Keys in Memory (Hacker News) Source: https://mathstodon.xyz/@iblech/116769502749142438 A critical vulnerability has been identified in Linux kernels since version 6.9, where Logical Unit Key (LUKS) disk encryption keys are no longer reliably wiped from memory when a system enters suspend mode. This flaw means that after resuming from suspend, or even during a 'cold boot' attack, a sophisticated attacker with physical access could potentially extract the disk encryption keys directly from the system's RAM. Prior to this, LUKS was designed to clear these sensitive keys, providing a layer of protection against memory forensics attacks. The issue fundamentally undermines the security posture of LUKS-encrypted systems that rely on suspend functionality. It poses a significant risk for users and organizations handling sensitive data on laptops or any device where physical access by an adversary is a concern. The practical implication is that suspending a Linux 6.9+ system with LUKS encryption may no longer be a secure operation, forcing users to fully shut down their machines to ensure key erasure. Mitigation strategies include avoiding suspend, reverting to an earlier kernel version if feasible, or diligently monitoring for official patches addressing this severe data leakage vector. Comment: This is a serious regression impacting fundamental data at rest security for Linux users, especially on laptops. If you use LUKS, avoid suspend on Linux 6.9+ until a fix is verif
