Disclosed a deserialization bypass vulnerability (F1) in fastjson2 ≤ 2.0.64 that can bypass AutoType blacklist validation; the official fix has been merged into the main branch but not yet released.

Security researcher Domas reveals rosenbridge, a hardware backdoor in VIA C3 x86 CPUs that allows unprivileged code to bypass processor protections and access kernel memory. The repository provides tools to check for and mitigate the vulnerability.

Framework Computer disclosed a data breach caused by exploitation of a Metabase 0-day vulnerability, highlighting security risks in third-party analytics tools.

Tencent's Corvus AI research pipeline discovered SCTPhantom, an 18-year-old use-after-free vulnerability in Linux SCTP dynamic address reconfiguration (ASCONF) that enables local privilege escalation. The article details the discovery, root cause, exploitation chain, and upstream fix.

Zapscape (CVE-2026-64561) is a KVM/x86 shadow MMU use-after-free vulnerability that allows a guest VM to escape to the host and execute code with kernel privileges. The published PoC demonstrates a full guest-to-host escape targeting AMD SVM/NPT on Linux 7.1.3, posing a serious threat to multi-tenant public clouds.

This research describes compiler-invented loads, where compiler optimizations create additional memory reads not present in source code, turning seemingly secure code into vulnerable binaries with TOCTOU races. It includes audits across kernels, hypervisors, enclaves, and firmware.
