Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the
mlx5e tx reporter timeout recover() function. The function attempts to access sq->netdev after mlx5e safe reopen channels() has already torn down and freed the channel and its embedded Send Queues (SQs). This occurs because the sq reference becomes invalid, whereas the priv reference remains safe during channel teardown.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
