Affected: AlmaLinux:9: device-mapper-multipath, AlmaLinux:9: device-mapper-multipath-devel, AlmaLinux:9: device-mapper-multipath-libs, AlmaLinux:9: kpartx

The device-mapper-multipath packages provide tools that use the device-mapper multipath kernel module to manage multipath devices.

Security Fix(es):

* device-mapper-multipath: multipathd: insecure handling of files in /dev/shm leading to symlink attack (CVE-2022-41973)

multipath-tools 0.7.7 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited in conjunction with CVE-2022-41974. Local users able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which could lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.

This package provides the multipath tool and the multipathd daemon to manage dm-multipath devices. multipath can detect and set up multipath maps. multipathd sets up multipath maps automatically,monitors path devices for failure, removal, or addition, and applies the necessary changes to the multipath maps to ensure continuous availability of the map devices.
