{"id":"CVE-2023-53652","summary":"vdpa: Add features attr to vdpa_nl_policy for nlattr length check","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nvdpa: Add features attr to vdpa_nl_policy for nlattr length check\n\nThe vdpa_nl_policy structure is used to validate the nlattr when parsing\nthe incoming nlmsg. It will ensure the attribute being described produces\na valid nlattr pointer in info-\u003eattrs before entering into each handler\nin vdpa_nl_ops.\n\nThat is to say, the missing part in vdpa_nl_policy may lead to illegal\nnlattr after parsing, which could lead to OOB read just like CVE-2023-3773.\n\nThis patch adds the missing nla_policy for vdpa features attr to avoid\nsuch bugs.","modified":"2026-03-20T12:33:16.488799Z","published":"2025-10-07T15:19:48.628Z","related":["SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4301-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53652.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44b508cc96889e61799cc0fc6c00766a54f3ab5a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/645d17e06c502e71b880b2b854930e5a64014640"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79c8651587504ba263d2fd67fd4406240fb21f69"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53652.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53652"},{"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":"90fea5a800c3dd80fb8ad9a02929bcef5fde42b8"},{"fixed":"44b508cc96889e61799cc0fc6c00766a54f3ab5a"},{"fixed":"645d17e06c502e71b880b2b854930e5a64014640"},{"fixed":"79c8651587504ba263d2fd67fd4406240fb21f69"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53652.json"}}],"schema_version":"1.7.5"}
