Vulnerability Title
RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction Upon RQ destruction if the firmware command fails which is the last resource to be destroyed some SW resources were already cleaned regardless of the failure. Now properly rollback the object to its original state upon such failure. In order to avoid a use-after free in case someone tries to destroy the object again, which results in the following kernel trace: refcount_t: underflow; use-after-free.
