CVE-2026-58086

FreeBSD 15.0 and 15.1 are affected by a privilege validation flaw in the ktrace(2) facility. An unrelated code change inadvertently caused PRIV_KTRACE to always be denied to a jailed root user, meaning tracing configured by that user was not flagged as privileged. As a result, an unprivileged use...

EUVD-2026-62340

As an inadvertent side effect of an unrelated code change, PRIVKTRACE 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 roo...

FreeBSD ktrace Information Disclosure Vulnerability

FreeBSD ktrace is a tool from the FreeBSD Foundation for tracing system calls. An information disclosure vulnerability exists in FreeBSD ktrace due to a flaw in the ktrace facility. An attacker can exploit the vulnerability to obtain the contents of kernel structure information...

CVE-2025-0662

In some cases, the ktrace facility will log the contents of kernel structures to userspace. In one such case, ktrace dumps a variable-sized sockaddr to userspace. There, the full sockaddr is copied, even when it is shorter than the full size. This can result in up to 14 uninitialized bytes of...

CVE-2025-0662

CVE-2025-0662 affects FreeBSD ktrace(2): the facility can log kernel structures to userspace and, in one case, dump a variable-sized sockaddr, copying the full sockaddr even when shorter, leaking up to 14 uninitialized bytes of kernel memory from a heap allocation to userspace. The issue is explo...

CVE-2024-6760

CVE-2024-6760 describes a logic bug in FreeBSD's ktrace which disables kernel tracing for setuid programs. The flaw allows unprivileged users to trace and inspect the behavior of setuid binaries, potentially reading files they normally should not access (e.g., the local password database). Connec...
