CVE-2026-23425

CVE-2026-23425 (Linux kernel KVM arm64) — The issue stems from non-protected pKVM guests where the hypervisor copies only the KVM_ARCH_FLAG_ID_REGS_INITIALIZED flag from the host to the hypervisor during pkvm_init_features_from_host, while the actual id_regs data are not initialized. This can cau...

Microsoft Xbox One Hacked

It's an impressive feat, over a decade after the box was released: Since reset glitching wasn't possible, Gaasedelen thought some voltage glitching could do the trick. So, instead of tinkering with the system rest pins the hacker targeted the momentary collapse of the CPU voltage rail. This was...
