{"id":"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-\u003ehandle in the ioctl caller's\ndrm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls\namdxdna_hwctx_sync_debug_bo(), but passes abo-\u003eclient.\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-\u003ehandle. The BO's stored\nclient pointer is object state, not the ioctl context.\n\nPass filp-\u003edriver_priv instead, matching the original handle lookup.","modified":"2026-08-18T03:56:37.280046716Z","published":"2026-08-15T05:52:37.524Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72090.json","cna_assigner":"Linux"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7ea0468380216c10b73633b976d33efa8c12d375"},{"fixed":"216e43d93dd49ec253052741aa476e51a8c54cd8"},{"fixed":"7caf2a2351d4053075670ff3e26a6815da0a9e1e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72090.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72090.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"}]}
