It validates bLength against\nbNumGrpTrmBlock before reading baAssoGrpTrmBlkID[], but not against the\nremaining bytes in the endpoint-extra scan.\n\nA malformed device can therefore make later baAssoGrpTrmBlkID[] reads\nconsume bytes past the walked descriptor.\n\nReject zero-length and overlong descriptors while walking endpoint\nextras.","modified":"2026-07-08T08:13:44.955987584Z","published":"2026-06-24T16:28:44.345Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52964.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/17e76b19de1aff5ff4de64d269290bd1b07a01d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/918be519c7876329e1b6e2ea1c59f0b75e792dca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a310b4bebda5e4a1b26520c0cc5145ccd6d617e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9c184a83574549a36ea69b755f650e57d164c78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fafc97bd01e4c737eaeafadfdadb1af4bbfa7307"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52964.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52964"},{"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":"ff49d1df79aef7580fe3ac99d17c3f886655d080"},{"fixed":"fafc97bd01e4c737eaeafadfdadb1af4bbfa7307"},{"fixed":"a310b4bebda5e4a1b26520c0cc5145ccd6d617e2"},{"fixed":"f9c184a83574549a36ea69b755f650e57d164c78"},{"fixed":"17e76b19de1aff5ff4de64d269290bd1b07a01d3"},{"fixed":"918be519c7876329e1b6e2ea1c59f0b75e792dca"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52964.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52964.json"}}],"schema_version":"1.7.5"}
