CVE-2022-42012 is a denial-of-service vulnerability affecting D-Bus versions before 1.12.24, 1.13.x before 1.14.4, and 1.15.x before 1.15.2, including various Fedora and Freedesktop D-Bus implementations. An authenticated attacker can crash the dbus-daemon and other libdbus-dependent programs by sending malformed messages with attached file descriptors. Rated Medium severity (CVSS 6.5), this vulnerability has a low attack complexity and requires authenticated access, leading to a high impact on availability. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
