Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix integer overflow in radeon_align_pitch() radeon_align_pitch() has the same kind of overflow issue as the old amdgpu helper: both the alignment round-up add and the final 'aligned * cpp' calculation can overflow signed int. If that wraps, radeon_mode_dumb_create() can end up returning an invalid pitch or creating a zero-sized dumb buffer. Fix this by using check_add_overflow() for the alignment round-up and check_mul_overflow() for the final pitch calculation, returning 0 on overflow. Also reject zero pitch and size in radeon_mode_dumb_create(). Found via AST-based call-graph analysis using sqry.

radeon_drm_ioctl() dispatches to radeon_mode_dumb_create() -\u003e radeon_align_pitch(), with no network, Bluetooth, or remote packet path to this legacy radeon KMS driver.\\nAC:L - An attacker fully controls width, height, and bpp in the ioctl and can pick values (e.g. width=0x3FFFFFC0, bpp=32) that pass generic drm_mode_create_dumb() checks yet wrap signed-int pitch math, deterministically yielding zero or invalid pitch without races or uncontrollable layout.\\nPR:L - Exploitation requires opening the primary DRM node (render clients are blocked because CREATE_DUMB lacks DRM_RENDER_ALLOW); typical access is via the video group or logind session ACLs, i.e. a low-privileged local account, not root/CAP_SYS_ADMIN in the init namespace.\\nUI:N - The attacker triggers the overflow from their own process by issuing CREATE_DUMB with crafted dimensions; no victim must mount filesystems, click links, or perform any separate action.\\nS:U - Impact is in-kernel GEM/TTM memory corruption and privilege escalation within the host kernel security boundary, not a KVM guest-to-host escape, IOMMU bypass, or other cross-authority scope change.\\nC:H - Signed-int overflow can return pitch 0 or a bogus u32 pitch while drm_mode_create_dumb() already validated a much larger stride, creating undersized VRAM/GTT GEM objects whose metadata mismatches actual backing, enabling out-of-bounds kernel reads of adjacent allocations.\\nI:H - A zero-sized or undersized dumb buffer paired with attacker-chosen width/height lets subsequent mmap, map_dumb, and GPU scanout paths treat the object as larger than allocated, corrupting adjacent kernel heap/VRAM objects and enabling control-flow hijack primitives.\\nA:H - Pre-fix code allocates zero-byte GEM objects on overflow instead of failing cleanly, and malformed pitch/size metadata can provoke kernel oopses, GPU faults, or repeatable denial of service when the BO is mapped or used for display.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"ff72145badb834e8051719ea66e024784d000cb4\", \"lessThan\": \"b7b44937c548c2c987fcdd129f8896741004bed6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ff72145badb834e8051719ea66e024784d000cb4\", \"lessThan\": \"415bb9893e249e46aa5159f7363a11512cf06fa9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ff72145badb834e8051719ea66e024784d000cb4\", \"lessThan\": \"d9dfa176899d488e48bb7342d2c43ddd36e66318\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ff72145badb834e8051719ea66e024784d000cb4\", \"lessThan\": \"dfc7b5b5599472277e71e5bd2712740651c7c5be\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ff72145badb834e8051719ea66e024784d000cb4\", \"lessThan\": \"ce3b24eb3ee8f82de851535f516bf21f83e82259\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/radeon/radeon_gem.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.39\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.39\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.145\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/radeon/radeon_gem.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/b7b44937c548c2c987fcdd129f8896741004bed6\"}, {\"url\": \"https://git.kernel.org/stable/c/415bb9893e249e46aa5159f7363a11512cf06fa9\"}, {\"url\": \"https://git.kernel.org/stable/c/d9dfa176899d488e48bb7342d2c43ddd36e66318\"}, {\"url\": \"https://git.kernel.org/stable/c/dfc7b5b5599472277e71e5bd2712740651c7c5be\"}, {\"url\": \"https://git.kernel.org/stable/c/ce3b24eb3ee8f82de851535f516bf21f83e82259\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm/radeon: fix integer overflow in radeon_align_pitch()\\n\\nradeon_align_pitch() has the same kind of overflow issue as the old\\namdgpu helper: both the alignment round-up add and the final\\n\u0027aligned * cpp\u0027 calculation can overflow signed int.\\n\\nIf that wraps, radeon_mode_dumb_create() can end up returning an\\ninvalid pitch or creating a zero-sized dumb buffer.\\n\\nFix this by using check_add_overflow() for the alignment round-up and\\ncheck_mul_overflow() for the final pitch calculation, returning 0 on\\noverflow.
