X.OrgThe DiscoveryMore severe vulnerabilities have been discovered in the widely used X.Org X11 server. These bugs include memory safety flaws, use-after-free vulnerabilities, and heap buffer overread issues that could leak sensitive data. |
XenThe DiscoveryA recently uncovered "Native Branch History Injection (BHI)" exploit against the Linux kernel signifies the ongoing battle against Spectre v2 vulnerabilities. Researchers have revealed that BHI can bypass existing Spectre v2/BHI mitigations to read sensitive data from the memory of Intel systems (CVE-2024-2201). |
Linux KernelThe DiscoveryResearchers have exposed new and sophisticated attacks that endanger the security and confidentiality of virtual machines (VMs). Two variations of Ahoi attacks, Heckler and WeSee, have been identified targeting hardware-based trusted execution environments, specifically AMD’s Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) and Intel’s Trust Domain Extensions (TDX) technologies. |
