CVE-2026-58086

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...

CVE-2026-58086

The FreeBSD kernel (versions 15.1 and 15.0) is vulnerable to a flaw where PRIV_KTRACE is always denied to a jailed root user. This incorrect validation occurs because a side effect of an unrelated code change prevents jailed root users from flagging tracing configurations as privileged. Consequen...

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

The FreeBSD ktrace facility contains an information disclosure vulnerability due to a flaw in how it handles variable-sized sockaddr structures. The facility copies the full structure to userspace even when it is shorter than the full size, resulting in the leakage of up to 14 uninitialized bytes...
