CVE-2022-3787 – device-mapper-multipath: Regression of CVE-2022-41974 fix in Red Hat Enterprise Linux

https://notcve.org/view.php?id=CVE-2022-3787

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. • https://bugzilla.redhat.com/show_bug.cgi?id=2138959 https://access.redhat.com/security/cve/CVE-2022-3787 • CWE-285: Improper Authorization •
