CVE-2026-53007

CVE-2026-53007 affects the Linux kernel ice driver. The vulnerability arises when ice_set_ringparam() clears tstamp_ring of temporary tx_rings without clearing ICE_TX_RING_FLAGS_TXTIME. If ICE_TX_RING_FLAGS_TXTIME is set and ice_setup_tx_ring() then fails, unwinding can dereference a NULL tstamp_...
