Kerentanan Improper Check for Dropped Privileges pada freebsd. Skor CVSS 3.1 8.1 (High) menurut CISA ADP.

Deskripsi (NVD)

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. An unprivileged user in a jail that has permission to debug the target process can modify the jailed root user's ktrace(2) flags, or disable tracing outright. A jailed root user therefore cannot reliably trace unprivileged processes.
