Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于未正确处理QP/RQ销毁时的固件返回结果，可能导致上层操作继续执行而实际销毁失败。

Vulnerability Title
RDMA/mlx5: Return the firmware result upon destroying QP/RQ
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Return the firmware result upon destroying QP/RQ Previously when destroying a QP/RQ, the result of the firmware destruction function was ignored and upper layers weren't informed about the failure. Which in turn could lead to various problems since when upper layer isn't aware of the failure it continues its operation thinking that the related QP/RQ was successfully destroyed while it actually wasn't, which could lead to the below kernel WARN. Currently, we return the correct firmware destruction status to upper layers which in case of the RQ would be mlx5_ib_destroy_wq() which was already capable of handling RQ destruction failure or in case of a QP to destroy_qp_common(), which now would actually warn upon qp destruction failure.
