"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hns3: fix double free issue for tx spare buffer\n\nIn hns3_set_ringparam(), a temporary copy (tmp_rings) of the ring structure\nis created for rollback. However, the tx_spare pointer in the original\nring handle is incorrectly left pointing to the old backup memory.\n\nLater, if memory allocation fails in hns3_init_all_ring() during the setup,\nthe error path attempts to free all newly allocated rings. Since tx_spare\ncontains a stale (non-NULL) pointer from the backup, it is mistaken for\na newly allocated buffer and is erroneously freed, leading to a double-free\nof the backup memory.\n\nThe root cause is that the tx_spare field was not cleared after its value\nwas saved in tmp_rings, leaving a dangling pointer.\n\nFix this by setting tx_spare to NULL in the original ring structure\nwhen the creation of the new `tx_spare` fails. This ensures the\nerror cleanup path only frees genuinely newly allocated buffers."
