Description

In the Linux kernel, the following vulnerability has been resolved: ice: set tx_tstamps when creating new Tx rings via ethtool When the user changes the number of queues via ethtool, the driver allocates new rings. This allocation did not initialize tx_tstamps. This results in the tx_tstamps field being zero (due to kcalloc allocation), and would result in a NULL pointer dereference when attempting a transmit timestamp on the new ring.

Affected products

• Linux kernel: 5.14 — fixed in 6.1

How to fix

Upgrade to a fixed version: Linux kernel 6.1. Check the vendor advisory for mitigations.
