  3. CVE-2023-53047
In the Linux kernel, the following vulnerability has been resolved: tee: amdtee: fix race condition in amdtee_open_session There is a potential race condition in amdtee_open_session that may lead to use-after-free. For instance, in amdtee_open_session() after sess->sess_mask is set, and before setting: sess->session_info[i] = session_info; if amdtee_close_session() closes this same session, then 'sess' data structure will be released, causing kernel panic when 'sess' is accessed within amdtee_open_session(). The solution is to set the bit sess->sess_mask as the last step in amdtee_open_session().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tee: amdtee: corrección de la condición de ejecución en amdtee_open_session. Existe una posible condición de ejecución en amdtee_open_session que podría provocar un use-after-free. Por ejemplo, en amdtee_open_session(), después de configurar sess->sess_mask y antes de configurar: sess->session_info[i] = session_info; si amdtee_close_session() cierra esta misma sesión, se liberará la estructura de datos 'sess', lo que provocará un pánico del kernel al acceder a 'sess' dentro de amdtee_open_session(). La solución es configurar el bit sess->sess_mask como último paso en amdtee_open_session().
