In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix leak of rcvhdrtail_dummy_kvaddr
This buffer is currently allocated in hfi1_init():
if (reinit) ret = init_after_reset(dd); else ret = loadtime_init(dd); if (ret) goto done;
/* allocate dummy tail memory for all receive contexts */ dd->rcvhdrtail_dummy_kvaddr = dma_alloc_coherent(&dd->pcidev->dev, sizeof(u64), &dd->rcvhdrtail_dummy_dma, GFP_KERNEL);
if (!dd->rcvhdrtail_dummy_kvaddr) { dd_dev_err(dd, "cannot allocate dummy tail memory\n"); ret = -ENOMEM; goto done; }
The reinit triggered path will overwrite the old allocation and leak it.
Fix by moving the allocation to hfi1_alloc_devdata() and the deallocation to hfi1_free_devdata().
