CVE-2026-77159: UNIX Symbolic Link (Symlink) Following

A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost function. The function uses a path-based chown on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd running as...

GHSA-F8G7-2XJC-7MFH rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination

Summary With -l/--links, rclone's local backend recreates a source .rclonelink object as a real symlink at the destination verbatim preserved by design for faithful backups. Directory-metadata application, however, does not go through the os.Root sandbox and does not use NOFOLLOW syscalls. A loca...

CVE-2026-88016 rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path...

CVE-2026-88924 Gvfs: gvfs-admin socket ownership race permits local root

A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check...

CVE-2026-88924

A Time-of-Check Time-of-Use (TOCTOU) race condition exists in the gvfsd-admin daemon of gvfs (GNOME Virtual Filesystem). The privileged daemon calls the link-following chown() on a socket pathname inside a user-controlled directory; a local attacker can replace that pathname with a symbolic link ...

CVE-2026-88265 Crun: crun: /dev/null symlink follow during stdio reopen allows host bind-mount write and chown

A flaw was found in crun. After pivotroot, reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed relea...

CVE-2026-88265

crun (a container runtime) is affected by a flaw where, after pivot_root , reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, allowing the container to change that file's ownership (chown). This effectively permits a host bind-mount write and chown from ...

mrtg: MRTG daemon symlink-following chown allows local privilege escalation via PID file path manipulation

A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link symlink following vulnerability. By influencing or pre-placing a symlink in the process ID PID file path, the attacker can trick...
