You Get What You Sample: Evaluating Sampling Strategies for Web Security Measurements

Web measurement studies rely on domain datasets such as Tranco to quantify the prevalence and impact of security issues at scale, but exhaustively analyzing these datasets is often infeasible because of the cost of advanced analysis techniques, requiring the use of sampling. Despite its widesprea...

From Fleet to Lab: Revisiting the Security and Complexity of Industrial Rowhammer Mitigation

This paper studies efficient and secure Rowhammer mitigation at the Memory-Controller MC. Rowhammer mitigation faces a fundamental tradeoff between tracking storage and mitigation rate: precise trackers such as Misra-Gries avoid unnecessary mitigations but require large CAM structures, whereas...

CVE-2026-72325

A flaw was found in the Linux kernel's performance monitoring unit PMU for AMD processors. When Secure Virtual Machine SVM is toggled on a CPU with active Last Branch Record LBR events, the system incorrectly attempts to enable Branch Sampling BRS on hardware that does not support it. This...

CVE-2026-72237

A flaw was found in the Linux kernel. A local user can exploit a vulnerability in the perf subsystem on AMD processors utilizing the Branch Sampling BRS feature. This flaw occurs because the software filtering mechanism for branch records only validates the branch-to address, leaving the...

CVE-2026-72325

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/core: Avoid enabling BRS from the SVM reload path Branch Sampling BRS and Last Branch Record LBR are mutually exclusive hardware features, and users of both are tracked via cpuc-lbrusers. When SVM is toggled on a CPU...
