  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Fix NULL pointer dereference in...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Fix NULL pointer dereference in dcn401_init_hw()  dcn401_init_hw() assumes that update_bw_bounding_box() is valid when entering the update path. However, the existing condition:    ((!fams2_enable \u0026\u0026 update_bw_bounding_box) || freq_changed)  does not guarantee this, as the freq_changed branch can evaluate to true independently of the callback pointer.  This can result in calling update_bw_bounding_box() when it is NULL.  Fix this by separating the update condition from the pointer checks and ensuring the callback, dc-\u003Eclk_mgr, and bw_params are validated before use.  Fixes the below: ../dc/hwss/dcn401/dcn401_hwseq.c:367 dcn401_init_hw() error: we previously assumed \u0027dc-\u003Eres_pool-\u003Efuncs-\u003Eupdate_bw_bounding_box\u0027 could be null (see line 362)  (cherry picked from commit 86117c5ab42f21562fedb0a64bffea3ee5fcd477)",
