{"id":"CVE-2025-40330","summary":"bnxt_en: Shutdown FW DMA in bnxt_shutdown()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Shutdown FW DMA in bnxt_shutdown()\n\nThe netif_close() call in bnxt_shutdown() only stops packet DMA.  There\nmay be FW DMA for trace logging (recently added) that will continue.  If\nwe kexec to a new kernel, the DMA will corrupt memory in the new kernel.\n\nAdd bnxt_hwrm_func_drv_unrgtr() to unregister the driver from the FW.\nThis will stop the FW DMA.  In case the call fails, call pcie_flr() to\nreset the function and stop the DMA.","modified":"2026-03-20T12:43:16.269042Z","published":"2025-12-09T04:09:47.251Z","related":["SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:20207-1","SUSE-SU-2026:20220-1","SUSE-SU-2026:20228-1","openSUSE-SU-2026:20145-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/40xxx/CVE-2025-40330.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1a8a15c3f71d1199d510ccba4bc201cbd2204048"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc7208ca805ae6062f353a4753467d913d963bc6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/40xxx/CVE-2025-40330.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40330"},{"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":"24d694aec139e9e0a31c60993db79bd8ad575afe"},{"fixed":"1a8a15c3f71d1199d510ccba4bc201cbd2204048"},{"fixed":"bc7208ca805ae6062f353a4753467d913d963bc6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-40330.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-40330.json"}}],"schema_version":"1.7.5"}
