Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the
mlx5 eswitch add termtbl rule() function in the Linux kernel, which is associated with the reuse of previously freed memory. This can potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability occurs when having multiple destinations with termination tables, and the second or subsequent ones fail, causing the driver to revert the usage of term tables without resetting the assignment in attr->dests[num vport dests].termtbl, leading to a use-after-free when releasing the rule.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
