For instance, in amdtee_open_session() after\nsess->sess_mask is set, and before setting:\n\n    sess->session_info[i] = session_info;\n\nif amdtee_close_session() closes this same session, then 'sess' data\nstructure will be released, causing kernel panic when 'sess' is\naccessed within amdtee_open_session().\n\nThe solution is to set the bit sess->sess_mask as the last step in\namdtee_open_session().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/02b296978a2137d7128151c542e84dc96400bc00","https://git.kernel.org/stable/c/a63cce9393e4e7dbc5af82dc87e68cb321cb1a78","https://git.kernel.org/stable/c/b3ef9e6fe09f1a132af28c623edcf4d4f39d9f35","https://git.kernel.org/stable/c/f632a90f8e39db39b322107b9a8d438b826a7f4f","https://git.kernel.org/stable/c/f8502fba45bd30e1a6a354d9d898bc99d1a11e6d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2023-53047","score":0.00148,"percentile":0.04019,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
