Traefik: tcp router clears read deadlines before tls forwarding, enabling stalled handshakes (Slowloris DOS)

Impact There is a potential vulnerability in Traefik managing TLS handshake on TCP routers. When Traefik processes a TLS connection on a TCP router, the read deadline used to bound protocol sniffing is cleared before the TLS handshake is completed. When a TLS handshake read error occurs, the code...

HCL BigFix Quantum Risk Analyzer has a certain validation process that provides overly descriptive error messages when it encounters malformed input which can allow an attacker to conduct more efficient reconnaissance and fine-tune automated fuzzing tools to produce valid input...

CVE-2025-68780

A scheduling flaw was found in the Linux kernel's SCHEDDEADLINE implementation. The cpudlclear function can incorrectly set the freecpus bit for an offline CPU. This causes deadline tasks to be pushed to powered-down CPUs, where they cannot execute, resulting in task starvation for SCHEDDEADLINE...
