Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to the mlx5 component of the Linux kernel and is caused by incorrect error handling in the mlx5 internal err ret value() function. This can lead to a denial of service when a destroy command is executed. The issue is fixed by updating the error handler for UCTX and UMEM to return OK instead of EIO in certain cases. The vulnerability affects the fast unload flow, where the device state is set to internal error, indicating that the driver has started the destroy process.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
