{"id":"CVE-2026-64601","aliases":[],"url":"https://o3.security/vulnerability/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.","published":"2026-08-06T07:13:53.926Z","modified":"2026-08-08T03:48:19.087523378Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.39"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:19.087523378Z"}}
