CVE-2026-45891

The CVE-2026-45891 issue affects Linux kernel networking for the hns3 driver. In hns3_set_ringparam(), a temporary copy of the ring is used for rollback, but the tx_spare pointer in the original ring is not cleared after saving its value in tmp_rings. If memory allocation fails during hns3_init_a...
