CVE-2022-41974

multipath-tools 0.7.0 hasta 0.9.x anteriores a 0.9.2 permite a los usuarios locales obtener acceso de root, explotado solo o junto con CVE-2022-41973. Los usuarios locales capaces de escribir en sockets de dominio UNIX pueden eludir los controles de acceso y manipular la configuración de rutas múltiples. Esto puede provocar una escalada de privilegios locales al root. Esto ocurre porque un atacante puede repetir una palabra clave, lo cual se maneja mal porque se usa ADD aritmética en lugar de bitwise OR.

A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a keyword, which is mishandled when arithmetic ADD is used instead of bitwise OR. This could lead to local privilege escalation to root.
