CVE-2023-54231

DMA-buffer leak via incomplete allocation-error cleanup

Published Dec 30, 2025 · Updated Dec 30, 2025

Memory leakage in the Linux kernel 6.3 through 6.3.1 allows attackers to cause unspecified impact via unspecified vectors. In drivers/net/ethernet/wangxun/libwx/wx_lib.c, wx_setup_rx_resources returns after wx_alloc_page_pool fails without freeing its coherent DMA buffer. Reachability requires page-pool allocation to fail during receive-resource setup; the published record documents only retained DMA memory and no resulting crash.
