CVE-2026-64293

CVE-2026-64293 affects the Linux kernel iommufd component. A 32-bit bound-check in iommufd_veventq_fops_read() uses sizeof(hdr) (size of the pointer) instead of sizeof(*hdr), causing under-count of the vEVENT header and potentially writing past the user buffer during header+data payload copy. Mul...

Rendering on Real Silicon: GPU Render-Timing As a Passive, AI-Resistant CAPTCHA Signal

Conventional CAPTCHAs pose puzzles that modern AI systems increasingly solve, while behavioral and cryptographic-attestation defenses carry privacy or enrollment costs. We investigate an orthogonal signal: the physical timing behavior of a client's GPU under a controlled WebGL rendering workload...
