"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callback\n\nWith clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),\nindirect call targets are validated against the expected function\npointer prototype to make sure the call target is valid to help mitigate\nROP attacks. If they are not identical, there is a failure at run time,\nwhich manifests as either a kernel panic or thread getting killed. A\nproposed warning in clang aims to catch these at compile time, which\nreveals:\n\n drivers/gpu/drm/amd/amdgpu/../pm/swsmu/amdgpu_smu.c:3008:29: error: incompatible function pointer types initializing 'int (*)(void *, uint32_t, long *, uint32_t)' (aka 'int (*)(void *, unsigned int, long *, unsigned int)') with an expression of type 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, uint32_t)' (aka 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, unsigned int)') [-Werror,-Wincompatible-function-pointer-types-strict]\n .odn_edit_dpm_table = smu_od_edit_dpm_table,\n ^~~~~~~~~~~~~~~~~~~~~\n 1 error generated.\n\nThere are only two implementations of ->odn_edit_dpm_table() in 'struct\namd_pm_funcs': smu_od_edit_dpm_table() and pp_odn_edit_dpm_table(). One\nhas a second parameter type of 'enum PP_OD_DPM_TABLE_COMMAND' and the\nother uses 'u32'. Ultimately, smu_od_edit_dpm_table() calls\n->od_edit_dpm_table() from 'struct pptable_funcs' and\npp_odn_edit_dpm_table() calls ->odn_edit_dpm_table() from 'struct\npp_hwmgr_func', which both have a second parameter type of 'enum\nPP_OD_DPM_TABLE_COMMAND'.\n\nUpdate the type parameter in both the prototype in 'struct amd_pm_funcs'\nand pp_odn_edit_dpm_table() to 'enum PP_OD_DPM_TABLE_COMMAND', which\ncleans up the warning."
