  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: use proper context for logging  The same as the rest of the code, get_ss_info_from_atombios() uses calc_pll_cs-\u003ectx-\u003elogger for logging. But calc_pll_cs-\u003ectx is initialized only later in calc_pll_max_vco_construct(). Therefore, any output using DC_LOG_SYNC() leads to a NULL pointer deference in get_ss_info_from_atombios().  According to Sashiko, the very same problem exists in dce112_get_pix_clk_dividers() and dcn3_get_pix_clk_dividers() too.  To avoid accessing the NULL context, use clk_src-\u003ebase.ctx-\u003elogger everywhere. That context in base is initialized earlier in dce110_clk_src_construct() and dce112_clk_src_construct(). Before get_ss_info_from_atombios() or Sashiko's get_pix_clk_dividers functions above are actually called. This is done by redefining DC_LOGGER to CTX-\u003elogger.  Before: dce110_clk_src_construct() did:  -\u003e sets clk_src-\u003ebase.ctx = ctx;  -\u003e ss_info_from_atombios_create()    -\u003e get_ss_info_from_atombios()   \u003c- uses calc_pll_cs-\u003ectx  # BOOM  -\u003e calc_pll_max_vco_construct()    \u003c- sets calc_pll_cs-\u003ectx  After: dce110_clk_src_construct() does:  -\u003e sets clk_src-\u003ebase.ctx = ctx;  -\u003e ss_info_from_atombios_create()    -\u003e get_ss_info_from_atombios()   \u003c- uses clk_src-\u003ebase.ctx  (cherry picked from commit 6f16fcbb0c46a87e3d9685407e906573d60104b0)",
