CVE-2022-41974: High severity IBM BM Security Guardium vulnerability
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.
Other sources
multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.
OpenSVC multipath-tools for Linux could allow a local authenticated attacker to execute arbitrary commands on the system, caused by an authorization bypass flaw in the multipathd daemon. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system.
