Abstract: TLB poisoning attacks take advantage of security issues of translation lookaside buffer (TLB) management on SEV processors in Secure Encrypted Virtualization (SEV) virtual machines (VMs). In various embodiments, a hypervisor may poison TLB entries between two processes of a SEV VM to compromise the integrity and confidentiality of the SEV VM. Variants of TLB poisoning attacks and end-to-end attacks are shown to be successful on both Advanced Micro Devices (AMD) SEV and SEV-Encrypted State (SEV-ES). Countermeasures for thwarting TLB poisoning attacks include hardware-enforced TLB flush processes and re-exec schemes that, among other things, prevent attackers from manipulating TLB entries and causing a privileged victim process to execute malicious code in an attempt to bypass a password authentication.

Abstract: The present disclosure provides an anti-infective and anti-adhesive wound dressing based on nonspecific adhesion to bacteria, which includes a micron-sized porous membrane with polyolefin contained in its surface and does not contain any bactericide. According to the disclosure, through targeted selection of a material and surface structure of the porous membrane, nonspecific adhesion to the bacteria on the wound surface can be formed by good adaptability of its own surface energy and the structure of the porous membrane to surface energy of the bacteria, preventing the bacteria from penetrating into wound tissues and thus realizing the anti-infection for the bacteria and the anti-adhesion to the wound. Furthermore, no bactericide is required to be added, which not only reduces infection of the wound, but also weakens factors which are not conducive to wound healing, such as aggravation of inflammation caused by bacterial toxin released after bacterial rupture in traditional sterilization mechanisms.
