Rewterz Threat Advisory – Multiple Linux Kernel Vulnerabilities

April 28, 2022

Severity

High

Analysis Summary

CVE-2022-29800, CVSS: 7

Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a TOCTOU race condition flaw in the networkd-dispatcher daemon in the systed component. By sending a specially-crafted request using a rogue D-Bus service, an authenticated attacker could exploit this vulnerability to execute arbitrary code with root privileges.

CVE-2022-29799, CVSS: 7.8

Linux Kernel could allow a local authenticated attacker to traverse directories on the system, caused by not sanitize the OperationalState or the AdministrativeState in the networkd-dispatcher daemon in the systemd component. An attacker could send a specially-crafted URL request containing “dot dot” sequences (/../) to write arbitrary files on the system.
