CVE-2024-53121: net/mlx5: fs, lock FTE when checking if active

Published Dec 2, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: fs, lock FTE when checking if active

The referenced commits introduced a two-step process for deleting FTEs:

- Lock the FTE, delete it from hardware, set the hardware deletion function to NULL and unlock the FTE. - Lock the parent flow group, delete the software copy of the FTE, and remove it from the xarray.

However, this approach encounters a race condition if a rule with the same match value is added simultaneously. In this scenario, fscore may set the hardware deletion function to NULL prematurely, causing a panic during subsequent rule deletions.

To prevent this, ensure the active flag of the FTE is checked under a lock, which will prevent the fscore layer from attaching a new steering rule to an FTE that is in the process of deletion.

    In the Linux kernel net/mlx5 fs_core flow-entry handling, check the FTE active flag while holding the FTE lock so a new steering rule cannot be attached while the FTE is being deleted; during deletion, lock the FTE, delete it from hardware, set the hardware deletion function to NULL, and then unlock the FTE.
