CVE-2026-53007

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: fix potential NULL pointer deref in error path of ice_set_ringparam()<br /> <br /> ice_set_ringparam nullifies tstamp_ring of temporary tx_rings, without<br /> clearing ICE_TX_RING_FLAGS_TXTIME bit.<br /> When ICE_TX_RING_FLAGS_TXTIME is set and the subsequent<br /> ice_setup_tx_ring() call fails, a NULL pointer dereference could happen<br /> in the unwinding sequence:<br /> <br /> ice_clean_tx_ring()<br /> -&gt; ice_is_txtime_cfg() == true (ICE_TX_RING_FLAGS_TXTIME is set)<br /> -&gt; ice_free_tx_tstamp_ring()<br /> -&gt; ice_free_tstamp_ring()<br /> -&gt; tstamp_ring-&gt;desc (NULL deref)<br /> <br /> Clear ICE_TX_RING_FLAGS_TXTIME bit to avoid the potential issue.<br /> <br /> Note that this potential issue is found by manual code review.<br /> Compile test only since unfortunately I don&amp;#39;t have E830 devices.
