"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix potential null pointer dereference in dc_dmub_srv\n\nFixes potential null pointer dereference warnings in the\ndc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()\nfunctions.\n\nIn both functions, the 'dc_dmub_srv' variable was being dereferenced\nbefore it was checked for null. This could lead to a null pointer\ndereference if 'dc_dmub_srv' is null. The fix is to check if\n'dc_dmub_srv' is null before dereferencing it.\n\nThus moving the null checks for 'dc_dmub_srv' to the beginning of the\nfunctions to ensure that 'dc_dmub_srv' is not null when it is\ndereferenced.\n\nFound by smatch & thus fixing the below:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:1167 dc_dmub_srv_is_hw_pwr_up() warn: variable dereferenced before check 'dc_dmub_srv' (see line 1164)"

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: corrige una posible desreferencia de puntero nulo en dc_dmub_srv. Corrige posibles advertencias de desreferencia de puntero nulo en las funciones dc_dmub_srv_cmd_list_queue_execute() y dc_dmub_srv_is_hw_pwr_up(). En ambas funciones, se estaba desreferenciando la variable 'dc_dmub_srv' antes de verificar si era nula. Esto podr\u00eda provocar una desreferencia del puntero nulo si 'dc_dmub_srv' es nulo. La soluci\u00f3n es comprobar si 'dc_dmub_srv' es nulo antes de eliminar la referencia a \u00e9l. Por lo tanto, se mueven las comprobaciones nulas de 'dc_dmub_srv' al comienzo de las funciones para garantizar que 'dc_dmub_srv' no sea nulo cuando se desreferencia. Encontrado por smatch y arreglando as\u00ed lo siguiente: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() advertencia: variable desreferenciada antes de verificar 'dc_dmub_srv' (ver l\u00ednea 128) drivers/ gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:1167 dc_dmub_srv_is_hw_pwr_up() advertencia: variable desreferenciada antes de verificar 'dc_dmub_srv' (ver l\u00ednea 1164)"
