CVE-2022-50710
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.
