{"id":"CVE-2026-72305","summary":"VDUSE: avoid leaking information to userspace","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nVDUSE: avoid leaking information to userspace\n\nThe bounceing is not necessarily page aligned, so current VDUSE can\nleak kernel information through mapping bounce pages to\nuserspace. Allocate bounce pages with __GFP_ZERO to avoid leaking\ninformation to userspace.","modified":"2026-08-25T03:51:36.588060080Z","published":"2026-08-15T05:55:22.914Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72305.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/00335df9da2011e095f846d645cc2e9fd2907659"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ae878f262bd1445c8c31511856a99962a05fe16"},{"type":"WEB","url":"https://git.kernel.org/stable/c/41e27a6aca608c9e04f091c29c420d03fafe0313"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e88c1bc3a41d9a260dd42bae8ad18fd4f35bbe1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/690fb82c4122f8c2656fa4f842275132771b68b9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c1523803445ee0348f62b77793266dd981596e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fde25641cbddd0c084e3320d08f755e7e6acfae5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72305.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72305"},{"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":"8c773d53fb7b64267b0f55c1d3517cb8c5e29b3c"},{"fixed":"41e27a6aca608c9e04f091c29c420d03fafe0313"},{"fixed":"3ae878f262bd1445c8c31511856a99962a05fe16"},{"fixed":"fde25641cbddd0c084e3320d08f755e7e6acfae5"},{"fixed":"5e88c1bc3a41d9a260dd42bae8ad18fd4f35bbe1"},{"fixed":"690fb82c4122f8c2656fa4f842275132771b68b9"},{"fixed":"00335df9da2011e095f846d645cc2e9fd2907659"},{"fixed":"9c1523803445ee0348f62b77793266dd981596e0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72305.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.217"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.184"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72305.json"}}],"schema_version":"1.9.0"}
