Kerentanan UNIX Symbolic Link (Symlink) Following. Skor CVSS 3.1 5.5 (Medium) menurut redhat.com.
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 root) to transfer ownership of an arbitrary file to the swtpm user.
