{"id":"CVE-2026-72090","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-72090","summary":"accel/amdxdna: Use caller client for debug BO sync","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: Use caller client for debug BO sync\n\namdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's\ndrm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls\namdxdna_hwctx_sync_debug_bo(), but passes abo->client.\n\namdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle\nnamespace for debug_bo_hdl and as the owner of the hardware context xarray.\nThose must match the file that supplied args->handle. The BO's stored\nclient pointer is object state, not the ioctl context.\n\nPass filp->driver_priv instead, matching the original handle lookup.","published":"2026-08-15T05:52:37.524Z","modified":"2026-08-16T03:48:31.793682716Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.1.5"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/216e43d93dd49ec253052741aa476e51a8c54cd8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7caf2a2351d4053075670ff3e26a6815da0a9e1e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72090.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72090"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:31.793682716Z"}}
