Linux Distros Unpatched Vulnerability : CVE-2026-15791

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A crafted message in the BuildKit low-level build API can be used to remove the contents of the /tmp directory. The action that can normally be used to delete...

Linux Distros Unpatched Vulnerability : CVE-2026-15792

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic. CVE-2026-15792 Note that Nessus relies o...

SUSE CVE-2026-15788

BuildKit's cache mount source= selector on Windows Container on Windows WCOW workers does not detect NTFS directory junctions placed inside the cache root. A build authored by an untrusted user on a WCOW-configured BuildKit daemon can read arbitrary host files reachable to the BuildKit daemon...

SUSE CVE-2026-15789

A custom client can produce such an upload request to the BuildKit daemon that files can escape from the BuildKit-controlled state directory. The client needs to have valid permissions to access the BuildKit control API to issue builds, e.g., bypass authentication, etc...

SUSE CVE-2026-15791

A crafted message in the BuildKit low-level build API can be used to remove the contents of the /tmp directory. The action that can normally be used to delete files inside the build container rootfs can escape into the real host temp directory...
