CVE-2022-50710 Details
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.
A vulnerability exists in the Linux kernel's Intel Ice driver, specifically in the handling of transmit (Tx) rings when the number of queues is changed via ethtool. The issue arises because the new Tx rings are allocated without properly initializing the transmit timestamps. This oversight leads to the timestamps being set to zero (due to the use of kcalloc for allocation), causing a NULL pointer dereference when a transmit timestamp is requested on the newly created ring.
Users can upgrade to the patched version of the Linux kernel available in the Linux kernel stable tree. Instructions for downloading the updated kernel can be found in the Linux kernel documentation.
