Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a use-after-free vulnerability in the ucma cleanup multicast function in the InfiniBand driver. This vulnerability can be exploited due to a race condition when the xa for each() function is not properly locked, allowing an attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is caused by the ucma cleanup multicast function accessing memory that has already been freed, leading to a use-after-free error.
