OESA-2026-3505 (CVE-2026-72693)

Vulnerability from osv_openeuler – Published: 2026-08-30 04:14 – Updated: 2026-08-30 04:14 – Source website

Summary

kbd security update

Details

The project contains tools for managing Linux console ,including Linux console,virtual terminals, keyboard, etc, mainly, what they do is loading console fonts and keyboard maps.

Security Fix(es):

openvt -u is intended to identify the owner of the current VT and then execute login as that user from a privileged context. In the documented kbrequest/init usage, the ownership test in authenticate_user() relies on stat("/proc/<pid>/fd/0"). stat() on /proc/<pid>/fd/0 follows the symlink to the underlying TTY device node. As a result, buf.st_uid reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to root or the getty owner after logout while an unprivileged process still has fd 0 attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the -u path executes a passwordless login as the selected user. In the documented kbrequest/init deployment using openvt -us, this can result in passwordless login -f root on the spawned VT.(CVE-2026-72693)

CVE-2026-72693 (GCVE-0-2026-72693)

Vulnerability from cvelistv5 – Published: 2026-08-11 08:39 – Updated: 2026-09-15 11:37

Title

Kbd: local privilege escalation in openvt via incorrect process owner verification allowing passwordless root login

Summary

`openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc/<pid>/fd/0")`. `stat()` on `/proc/<pid>/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path.

          "value": "`openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat(\"/proc/\u003cpid\u003e/fd/0\")`. `stat()` on `/proc/\u003cpid\u003e/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path."
