{"id":"CVE-2026-64464","summary":"xhci: sideband: fix ring sg table pages leak","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxhci: sideband: fix ring sg table pages leak\n\nxhci_ring_to_sgtable() allocates a temporary pages array and\nuses it to build the returned sg_table with\nsg_alloc_table_from_pages().\n\nThe error paths free the pages array, but the success path\nreturns the sg_table without freeing it. This leaks the temporary\narray every time a sideband client gets an endpoint or event ring\nbuffer.\n\nFree the pages array after sg_alloc_table_from_pages() succeeds.\nThe returned sg_table has its own scatterlist entries and does not\ndepend on the temporary array after construction.","modified":"2026-07-27T04:03:19.773936155Z","published":"2026-07-25T08:51:30.443Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64464.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/49f6e3c3ef19f04f6657ed8dce550e36c763abb8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99d00a9e35e311a91d258029d5bb584377296c34"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3eaf82ff842d6ca95937ea584417e04828235a6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64464.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64464"},{"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":"de66754e9f8029f8ae955a588959b99cab56b506"},{"fixed":"99d00a9e35e311a91d258029d5bb584377296c34"},{"fixed":"a3eaf82ff842d6ca95937ea584417e04828235a6"},{"fixed":"49f6e3c3ef19f04f6657ed8dce550e36c763abb8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64464.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64464.json"}}],"schema_version":"1.7.5"}
