Issue Overview: x509.Certificate.VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name SAN entries. This caused strings.Splithost, "." to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically bas...

CVE-2026-48749

A flaw was found in Incus, a container and virtual machine manager. A crafted container image can use a symlink in the rootfs directory to read or write arbitrary files on the host, potentially leading to command execution. Mitigation No mitigation is needed as Incus is not shipped in any Red Hat...

AZL-95985 CVE-2026-47766 affecting package crun 1.24-6

crun is an open source OCI Container Runtime fully written in C. Prior to version 1.28, crun's default device setup opens the container rootfs /dev directory without ONOFOLLOW. If an OCI bundle contains rootfs/dev as a symlink and the bundle configuration does not mount /dev, crun follows that...

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...

runc: Malicious image with /dev symlink can trigger limited host filesystem integrity violations

Impact When setting up the container rootfs, setupPtmx and setupDevSymlinks call os.Remove and os.Symlink with a filepath.Join string which allow an image with /dev as a symlink to trick runc into deleting files called ptmx on the host or creating a hardcoded set of symlinks with specific names a...
