CVE-2021-26393 describes an insufficient memory cleanup vulnerability within the AMD Secure Processor (ASP) Trusted Execution Environment (TEE), affecting AMD products. An authenticated attacker with privileges could exploit this to generate a valid signed Trusted Application (TA) and potentially inject attacker-controlled data into process memory, leading to a loss of confidentiality. Rated 5.5 MEDIUM (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), this local attack requires low complexity and privileges, with a high impact on confidentiality. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
