CVE-2022-48841

Summary

CVE-2022-48841 is a vulnerability affecting the Linux kernel where a NULL pointer dereference can occur in the `ice_update_vsi_tx_ring_stats()` function. This issue arises when the routine attempts to update Tx ring stats with a NULL pointer. The consequences of this vulnerability are that the system may crash or be susceptible to arbitrary code execution. To address this issue, developers have modified the logic to move on to the next ring when encountering a NULL pointer instead of attempting to access it.
