{"id":"CVE-2025-38533","summary":"net: libwx: fix the using of Rx buffer DMA","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: libwx: fix the using of Rx buffer DMA\n\nThe wx_rx_buffer structure contained two DMA address fields: 'dma' and\n'page_dma'. However, only 'page_dma' was actually initialized and used\nto program the Rx descriptor. But 'dma' was uninitialized and used in\nsome paths.\n\nThis could lead to undefined behavior, including DMA errors or\nuse-after-free, if the uninitialized 'dma' was used. Althrough such\nerror has not yet occurred, it is worth fixing in the code.","modified":"2026-04-02T12:48:01.298488Z","published":"2025-08-16T11:12:25.978Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03601-1","SUSE-SU-2025:03602-1","SUSE-SU-2025:03633-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:3725-1","SUSE-SU-2025:3751-1","openSUSE-SU-2025:20081-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38533.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/027701180a7bcb64c42eab291133ef0c87b5b6c5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/05c37b574997892a40a0e9b9b88a481566b2367d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5fd77cc6bd9b368431a815a780e407b7781bcca0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ba7c793f96c1c2b944bb6f423d7243f3afc30fe9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38533.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38533"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3c47e8ae113a68da47987750d9896e325d0aeedd"},{"fixed":"027701180a7bcb64c42eab291133ef0c87b5b6c5"},{"fixed":"ba7c793f96c1c2b944bb6f423d7243f3afc30fe9"},{"fixed":"05c37b574997892a40a0e9b9b88a481566b2367d"},{"fixed":"5fd77cc6bd9b368431a815a780e407b7781bcca0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38533.json"}}],"schema_version":"1.7.5"}
