CVE-2026-58086

*** Pendiente de traducción *** As an inadvertent side effect of an unrelated code change, PRIV_KTRACE was always denied to a jailed root user. Tracing configured by a jailed root user was therefore not flagged as privileged.<br /> <br /> An unprivileged user in a jail that has permission to debug the target process can modify the jailed root user&amp;#39;s ktrace(2) flags, or disable tracing outright. A jailed root user therefore cannot reliably trace unprivileged processes.
