TQPs 0-1023 and TQPs\n1024-1279 are in different BAR space addresses. However,\nhclge_fetch_pf_reg does not distinguish the tqp space information when\nreading the tqp space information. When the number of TQPs is greater\nthan 1024, access bar space overwriting occurs.\nThe problem of different segments has been considered during the\ninitialization of tqp.io_base. Therefore, tqp.io_base is directly used\nwhen the queue is read in hclge_fetch_pf_reg.\n\nThe error message:\n\nUnable to handle kernel paging request at virtual address ffff800037200000\npc : hclge_fetch_pf_reg+0x138/0x250 [hclge]\nlr : hclge_get_regs+0x84/0x1d0 [hclge]\nCall trace:\n hclge_fetch_pf_reg+0x138/0x250 [hclge]\n hclge_get_regs+0x84/0x1d0 [hclge]\n hns3_get_regs+0x2c/0x50 [hns3]\n ethtool_get_regs+0xf4/0x270\n dev_ethtool+0x674/0x8a0\n dev_ioctl+0x270/0x36c\n sock_do_ioctl+0x110/0x2a0\n sock_ioctl+0x2ac/0x530\n __arm64_sys_ioctl+0xa8/0x100\n invoke_syscall+0x4c/0x124\n el0_svc_common.constprop.0+0x140/0x15c\n do_el0_svc+0x30/0xd0\n el0_svc+0x1c/0x2c\n el0_sync_handler+0xb0/0xb4\n el0_sync+0x168/0x180","state":0,"publishedAt":"2025-01-19T10:18:07.976+00:00","modifiedAt":"2026-10-21T12:35:53.165+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_regs.c\",\n \"drivers/net/ethernet/hisilicon/hns3/hns3vf/hclgevf_regs.c\"\n ],\n \"versions\": [\n {\n \"version\": \"939ccd107ffcade20c9c7055a2e7ae0fd724fb72\",\n \"lessThan\": \"a85246635466752b9af72188e4a839541120d952\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"939ccd107ffcade20c9c7055a2e7ae0fd724fb72\",\n \"lessThan\": \"0575baa733fc4219f230aef22d5bc35d922f1e9a\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"939ccd107ffcade20c9c7055a2e7ae0fd724fb72\",\n \"lessThan\": \"7997ddd46c54408bcba5e37fe18b4d832e45d4d4\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"df34972a33d268a7113c119fe4e4b07a6819aa0c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"2b1fff96a297034f03466cfecda9824adafe16ed\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6.4.16\",\n \"lessThan\": \"6.5\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.5.3\",\n \"lessThan\": \"6.6\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_regs.c\",\n \"drivers/net/ethernet/hisilicon/hns3/hns3vf/hclgevf_regs.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6.6\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"6.6\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.160\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.10\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.13\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/a85246635466752b9af72188e4a839541120d952","https://git.kernel.org/stable/c/0575baa733fc4219f230aef22d5bc35d922f1e9a","https://git.kernel.org/stable/c/7997ddd46c54408bcba5e37fe18b4d832e45d4d4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-21650","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-21650","identifiers":["CVE-2025-21650"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
