Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 5.14.0-408.el9.x86 64
Description:
The vulnerability is related to the RDMA/qedr component of the Linux kernel. It is caused by an error in the qedr create user qp function, which can lead to a denial of service. The issue arises when the qedr init user queue function fails, and the allocated resources are not properly freed. This can cause a warning and potentially lead to a system crash. The vulnerability is identified by the function names
qedr create user qp() and qedr init user queue(), and the uverbs destroy ufile hw() function is also involved.Recommendations:
To resolve this issue, update the Linux kernel to a version that includes the fix for the RDMA/qedr error flow, ensuring that the allocated resources are properly freed in case of a failure in the
qedr init user queue() function. As a temporary workaround, consider disabling the qedr create user qp() function until a patch is available.Exploit
