CVE-2026-64327

CVE-2026-64327 affects the Linux kernel USB gadget f_fs (FunctionFS) component. The root cause is that epfile->in was only initialized in ffs_func_eps_enable() (triggered on USB host connection), so early userspace ioctls such as FUNCTIONFS_DMABUF_ATTACH executed before host connection would o...

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...

Open WebUI: Account enumeration via observable login timing discrepancy

Summary The /api/v1/auths/signin endpoint leaked whether an email address belonged to a registered account through a response-time side channel. Password verification ran bcrypt only when the email was found in the database; for a non-existent email the request returned early without hashing. The...

CVE-2026-64253

CVE-2026-64253 affects the Linux kernel and relates to process creation via fork. The root cause is that in copy_process(), PF_BLOCK_TS can be inherited from the parent while the child’s plug pointer is cleared, breaking the invariant that PF_BLOCK_TS set implies current->plug != NULL. The fix...

USN-8601-1 pam vulnerability

It was discovered that PAM had a timing discrepancy in the pamuserdb module when comparing plaintext passwords. An attacker could possibly use this issue to obtain sensitive information by measuring response-timing differences during repeated authentication attempts...
