Description
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.
