CVE-2022-41974: Debian Linux

High severity, CVSS 7.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 10.0 only; version 11.0 only
• Fedoraproject Fedora: version 36 only
• Opensvc Multipath-Tools: from 0.7.0, before 0.9.2 (fixed in 0.9.2)
