NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-core package and not the kernel-debug-core package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device

In case devcom allocation is failed, mlx5 is always freeing the priv. However, this priv might have been allocated by a different thread, and freeing it might lead to use-after-free bugs. Fix it by freeing the priv only in case it was allocated by the running thread.
