- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: dev_ioctl: take ops lock in hwtstamp lower paths
ndo hwtstamp callbacks are expected to run under the per-device ops lock. Make the lower get/set paths consistent with the rest of ndo invocations.

Note that the mlx5hwtstampset and mlx5ehwtstampset functions shown in the trace come from an in progress patch converting the legacy ioctl to ndohwtstampget/set and are not present in mainline.
