Description

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().

Affected configurations

• linux linux kernel (>= 5.6 < 5.10.177) • linux linux kernel (>= 5.11 < 5.15.105) • linux linux kernel (>= 5.16 < 6.1.22) • linux linux kernel (>= 6.2 < 6.2.9) • linux linux kernel 6.3
