Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ice: fix NULL pointer dereference in ice_update_vsi_tx_ring_stats()

It is possible to do NULL pointer dereference in routine that updates
Tx ring stats. Currently only stats and bytes are updated when ring
pointer is valid, but later on ring is accessed to propagate gathered Tx
stats onto VSI stats.

Change the existing logic to move to next ring when ring is NULL.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ice: corrige la desreferencia del puntero NULL en ice_update_vsi_tx_ring_stats() Es posible realizar la desreferencia del puntero NULL en la rutina que actualiza las estadísticas del anillo Tx. Actualmente, solo se actualizan las estadísticas y los bytes cuando el puntero del anillo es válido, pero más adelante se accede al anillo para propagar las estadísticas de Tx recopiladas en las estadísticas de VSI. Cambie la lógica existente para pasar al siguiente anillo cuando el anillo sea NULL.
