CVE-2026-53007

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

ice: fix potential NULL pointer deref in error path of ice_set_ringparam()

ice_set_ringparam nullifies tstamp_ring of temporary tx_rings, without

clearing ICE_TX_RING_FLAGS_TXTIME bit.

When ICE_TX_RING_FLAGS_TXTIME is set and the subsequent

ice_setup_tx_ring() call fails, a NULL pointer dereference could happen

in the unwinding sequence:

ice_clean_tx_ring()

-> ice_is_txtime_cfg() == true (ICE_TX_RING_FLAGS_TXTIME is set)

-> ice_free_tx_tstamp_ring()

-> ice_free_tstamp_ring()

-> tstamp_ring->desc (NULL deref)

Clear ICE_TX_RING_FLAGS_TXTIME bit to avoid the potential issue.

Note that this potential issue is found by manual code review.

Compile test only since unfortunately I don't have E830 devices.
