The vq->log_base is from QEMU userpace and can be\nreclaimed via gfree(). As a result, this causes invalid memory writes to\nQEMU userspace.\n\nThe control queue path has the same issue.\n\ud83d\udccf Published: 2025-06-18T09:33:50.006Z\n\ud83d\udccf Modified: 2025-06-18T09:33:50.006Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/ca85c2d0db5f8309832be45858b960d933c2131c\n2. https://git.kernel.org/stable/c/bd8c9404e44adb9f6219c09b3409a61ab7ce3427\n3. https://git.kernel.org/stable/c/c0039e3afda29be469d29b3013d7f9bdee136834\n4. https://git.kernel.org/stable/c/f591cf9fce724e5075cc67488c43c6e39e8cbe27", "creation_timestamp": "2025-06-18T10:40:04.000000Z"}, {"uuid": "7a43e96d-ba1e-49e6-97cb-bb86c4c46c6b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2025-38074", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lruw7ln7jr23", "content": "", "creation_timestamp": "2025-06-18T11:36:44.702494Z"}]}
