CVE-2025-64437 KubeVirt Isolation Detection Flaw Allows Arbitrary File Permission Changes

KubeVirt is a virtual machine management add-on for Kubernetes. In versions before 1.5.3 and 1.6.1, the virt-handler does not verify whether the launcher-sock is a symlink or a regular file. This oversight can be exploited, for example, to change the ownership of arbitrary files on the host node ...

CVE-2025-64437

KubeVirt (virt-handler) vulnerability CVE-2025-64437 affects versions before 1.5.3 and 1.6.1. The issue is that virt-handler does not verify whether the launcher-sock is a symlink or a regular file, allowing an attacker who controls the virt-launcher pod’s filesystem to change ownership of arbitr...

CVE-2025-12418

Potential Denial of Service issue in all supported versions of Revenera InstallShield version 2025 R1, 2024 R2, 2023 R2, and prior. When e.g., a local administrator performs an uninstall, a symlink may get followed on removal of a user writeable configuration directory and induce a Denial of...

CVE-2025-12418

CVE-2025-12418 affects Revenera InstallShield (versions 2025 R1, 2024 R2, 2023 R2 and earlier). The issue arises when a local administrator uninstalls and a symlink is followed during removal of a user-writable configuration directory, potentially causing Denial of Service. The root cause is rela...

runc: container escape with malicious config due to /dev/console mount and related races

A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console bind-mounts. When creating the /dev/console bind-mount to /dev/pts/$n, if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount...

runc: container escape via 'masked path' abuse due to mount race conditions

A flaw was found in runc. This flaw exploits an issue with how masked paths are implementedin runc. When masking files, runc will bind-mount the container's /dev/null inode on top of the file. However, if an attacker can replace /dev/null with a symlink to some other procfs file, runc will instea...

KubeVirt Isolation Detection Flaw Allows Arbitrary File Permission Changes

Summary Short summary of the problem. Make the impact and severity as clear as possible. It is possible to trick the virt-handler component into changing the ownership of arbitrary files on the host node to the unprivileged user with UID 107 due to mishandling of symlinks when determining the roo...

KubeVirt Arbitrary Container File Read

Summary Short summary of the problem. Make the impact and severity as clear as possible. Mounting a user-controlled PVC disk within a VM allows an attacker to read any file present in the virt-launcher pod. This is due to erroneous handling of symlinks defined within a PVC. Details Give all detai...

Symlink Validation Bypass

tar-fs is vulnerable to symlink validation bypass. The vulnerability is due to improper validation of symbolic links during tar extraction, which allows an attacker to overwrite arbitrary files if the destination directory is predictable with a crafted tarball...
