  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/exynos: vidi: use ctx-\u003Elock to protect struct vidi_context member variables related to memory alloc/free  Exynos Virtual Display driver performs memory alloc/free operations without lock protection, which easily causes concurrency problem.  For example, use-after-free can occur in race scenario like this: \u0060\u0060\u0060 \tCPU0\t\t\t\tCPU1\t\t\t\tCPU2 \t----\t\t\t\t----\t\t\t\t----   vidi_connection_ioctl()     if (vidi-\u003Econnection) // true       drm_edid = drm_edid_alloc(); // alloc drm_edid       ...       ctx-\u003Eraw_edid = drm_edid;       ... \t\t\t\t\t\t\t\tdrm_mode_getconnector() \t\t\t\t\t\t\t\t  drm_helper_probe_single_connector_modes() \t\t\t\t\t\t\t\t    vidi_get_modes() \t\t\t\t\t\t\t\t      if (ctx-\u003Eraw_edid) // true \t\t\t\t\t\t\t\t        drm_edid_dup(ctx-\u003Eraw_edid); \t\t\t\t\t\t\t\t          if (!drm_edid) // false \t\t\t\t\t\t\t\t          ... \t\t\t\tvidi_connection_ioctl() \t\t\t\t  if (vidi-\u003Econnection) // false \t\t\t\t    drm_edid_free(ctx-\u003Eraw_edid); // free drm_edid \t\t\t\t    ... \t\t\t\t\t\t\t\t          drm_edid_alloc(drm_edid-\u003Eedid) \t\t\t\t\t\t\t\t            kmemdup(edid); // UAF!! \t\t\t\t\t\t\t\t            ... \u0060\u0060\u0060  To prevent these vulns, at least in vidi_context, member variables related to memory alloc/free should be protected with ctx-\u003Elock.",
