{"id":"CVE-2022-50844","summary":"drm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callback","details":"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 -\u003eodn_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-\u003eod_edit_dpm_table() from 'struct pptable_funcs' and\npp_odn_edit_dpm_table() calls -\u003eodn_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.","modified":"2026-03-20T12:22:38.660050Z","published":"2025-12-30T12:11:01.928Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0617-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50844.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/24cba9d865157c9e23128fbcf8b86f5da9570edd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36217f676b55932a12d6732c95388150015fdee6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e4d0ef752081e7aa6ffb7ccac11c499c732a2e05"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9084e9930db562bdcd47fa199a66fb45e16dab5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50844.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50844"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8f4828d0a104d961d5eb850d0aef1530fc24e370"},{"fixed":"f9084e9930db562bdcd47fa199a66fb45e16dab5"},{"fixed":"24cba9d865157c9e23128fbcf8b86f5da9570edd"},{"fixed":"36217f676b55932a12d6732c95388150015fdee6"},{"fixed":"e4d0ef752081e7aa6ffb7ccac11c499c732a2e05"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50844.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"5.15.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50844.json"}}],"schema_version":"1.7.5"}
