Since\namdgpu_bo_create_kernel() does not zero-initialize the buffer, when a\nsingle PTE is written the TLB may speculatively load other uninitialized\nentries from the same cacheline. Those garbage entries can appear valid,\nand a subsequent write to another PTE in the same cacheline may cause the\nGPU to use a stale garbage PTE from the TLB.\n\nFix this by calling memset_io() to zero-initialize the GART table with\ngart_pte_flags immediately after allocation.\n\nUsing AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work\nsince SDMA needs GART to be initialized to work.\n\n(cherry picked from commit d9af8263b82b6eaa60c5718e0c6631c5037e4b24)"}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c"], "versions": [{"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "40df11255d71b02e20e70579f1b12b687e396e26", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "91fbb5e635c8fb1b49e15c19da06480089ef719f", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "8ae8b9e74bab94aab1d79f1688129bcc61c8b29a", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "b17175d0a375b3ed5e81597dac4983fdb46e478d", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "791941be5da125d9a1b228582bfdc300c05d05b3", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "e6c2e6c2e1fa066968a16aca1cb66cd1bdde7741", "status": "affected", "versionType": "git"}, {"version": "0", "lessThan": "6.1.175", "status": "affected", "versionType": "semver"}, {"version": "0", "lessThan": "6.6.140", "status": "affected", "versionType": "semver"}, {"version": "0", "lessThan": "6.12.90", "status": "affected", "versionType": "semver"}, {"version": "0", "lessThan": "6.18.32", "status": "affected", "versionType": "semver"}, {"version": "0", "lessThan": "7.0.9", "status": "affected", "versionType": "semver"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c"], "versions": [{"version": "6.1.175", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.140", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.90", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.32", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.9", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "6.1.175"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "6.6.140"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "6.12.90"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "6.18.32"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "7.0.9"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/40df11255d71b02e20e70579f1b12b687e396e26"}, {"url": "https://git.kernel.org/stable/c/91fbb5e635c8fb1b49e15c19da06480089ef719f"}, {"url": "https://git.kernel.org/stable/c/8ae8b9e74bab94aab1d79f1688129bcc61c8b29a"}, {"url": "https://git.kernel.org/stable/c/b17175d0a375b3ed5e81597dac4983fdb46e478d"}, {"url": "https://git.kernel.org/stable/c/791941be5da125d9a1b228582bfdc300c05d05b3"}, {"url": "https://git.kernel.org/stable/c/e6c2e6c2e1fa066968a16aca1cb66cd1bdde7741"}], "title": "drm/amdgpu: zero-initialize GART table on allocation", "x_generator": {"engine": "bippy-1.2.0"}}}}
