{"id":"CVE-2026-64601","summary":"ALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission\n\nIn capture_urb_complete(), usb_anchor_urb() is called on every\ncompletion callback, but the URB is already anchored from the\ninitial submission in tascam_trigger_start(). Each redundant call\ncorrupts the anchor's doubly-linked list and inflates the URB\nrefcount. When usb_kill_anchored_urbs() traverses the list during\nstream stop / suspend / disconnect, the corrupted list leads to\nuse-after-free.\n\nRemove the redundant usb_anchor_urb() from the resubmit path.","modified":"2026-08-12T03:51:20.123627430Z","published":"2026-08-06T07:13:53.926Z","related":["openSUSE-SU-2026:11476-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64601.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/16f14f55141d4c55c3f321f93c328fff7cd6860a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5cff1529a2f9b3461a7f5a6e36a86682fc290534"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab1db64912428cdf06a4f9542e16e0575e9ad59f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64601.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64601"},{"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":"c1bb0c13e430623c26543baae5bb9ae21139db87"},{"fixed":"16f14f55141d4c55c3f321f93c328fff7cd6860a"},{"fixed":"ab1db64912428cdf06a4f9542e16e0575e9ad59f"},{"fixed":"5cff1529a2f9b3461a7f5a6e36a86682fc290534"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64601.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"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-2026-64601.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
