The reference count is 0, so the\n dma_buf is destroyed, which in turn decrements the corresponding\n amdgpu_bo reference count to 0, and the amdgpu_bo is destroyed -\n calling drm_gem_object_release then dma_resv_fini (which destroys the\n reservation object), then finally freeing the amdgpu_bo.\n\n- nouveau_bo obj->bo.base.resv is now a dangling pointer to the memory\n formerly allocated to the amdgpu_bo.\n\n- nouveau_gem_object_del calls ttm_bo_put(&nvbo->bo) which calls\n ttm_bo_release, which schedules ttm_bo_delayed_delete.\n\n- ttm_bo_delayed_delete runs and dereferences the dangling resv pointer,\n resulting in a general protection fault.\n\nFix this by moving the drm_prime_gem_destroy call from\nnouveau_gem_object_del to nouveau_bo_del_ttm. This ensures that it will\nbe run after ttm_bo_delayed_delete.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "706868a1a1072cffd8bd63f7e161d79141099849" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "47761deabb69a5df0c2c4ec400d80bb3e072bd2e" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "ada78110b2d3ec88b398a49703bd336d4cee7a08" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "12b038d521c75e3521522503becf3bc162628469" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "31e94c7989572f96926673614a3b958915a13ca9" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "6e2c805996a49998d31ac522beb1534ca417e761" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "6b95947ee780f4e1fb26413a1437d05bcb99712b" }, { "version": "22b33e8ed0e38b8ddcf082e35580f2e67a3a0262", "status": "affected", "versionType": "git", "lessThan": "8ec0fbb28d049273bfd4f1e7a5ae4c74884beed3" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "3.5", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "3.5" }, { "version": "5.4.293", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.4.*" }, { "version": "5.10.237", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.181", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.135", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.88", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.25", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.14.4", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.14.*" }, { "version": "6.15", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
