Affected by this vulnerability is the function sys_device_close/sys_device_control/sys_device_find/sys_device_init/sys_device_open/sys_device_read/sys_device_register/sys_device_write/sys_event_delete/sys_event_recv/sys_event_send/sys_mb_delete/sys_mb_recv/sys_mb_send/sys_mb_send_wait/sys_mq_recv/sys_mq_send/sys_mq_urgent/sys_mutex_delete/sys_mutex_release/sys_mutex_take/sys_rt_timer_control/sys_rt_timer_delete/sys_rt_timer_start/sys_rt_timer_stop/sys_sem_delete/sys_sem_release/sys_sem_take/sys_shmat/sys_shmdt/sys_thread_create/sys_thread_delete/sys_thread_startup/sys_timer_delete/sys_timer_gettime/sys_timer_settime of the file rt-thread/components/lwp/lwp_syscall.c. The manipulation of the argument arg[0] leads to information disclosure. An attack has to be approached locally.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
