Description

A flaw was found in the Linux kernel's ice driver. This vulnerability occurs due to a potential NULL pointer dereference in the ice_set_ringparam() function. When tstamp_ring of temporary tx_rings is nullified without clearing the ICE_TX_RING_FLAGS_TXTIME bit, and a subsequent ice_setup_tx_ring() call fails, it can lead to a system crash. This issue could allow a local attacker to cause a Denial of Service (DoS).
