Attaching the evidence requested by the kernel bug reporting guidelines, in one file: - version.log (/proc/version_signature + /proc/version) - lspci-vnvn.log (hardware inventory) - oops-evidencia.txt (the kernel signature lines from the crashed boot) - journal-fim-do-boot.txt (last 300 lines of the boot that froze)All sanitised: MAC addresses, private IPs, hostname, username and disk UUID removed.Note the version_signature: Ubuntu 7.0.0-38.38~24.04.4-generic, upstream base 7.0.14 - newer than the 7.0.10 where the epoll UAF fix (CVE-2026-46242) landed, and ep_remove_file() is indeed present in kallsyms, which is why I believe this is a sibling fault on the plain poll() path.
