{"id":"CVE-2026-80541","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80541","summary":"drm/amdgpu: validate GEM_CREATE domain combinations","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: validate GEM_CREATE domain combinations\n\nAMDGPU_GEM_CREATE checked domain bits against AMDGPU_GEM_DOMAIN_MASK,\nbut did not validate domain combinations. Userspace could combine\nCPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA, making\namdgpu_bo_placement_from_domain() exceed AMDGPU_BO_MAX_PLACEMENTS and\nhit BUG_ON().\n\nAllow combinations only within CPU/GTT/VRAM, and require non-CPU/GTT/\nVRAM domains to be specified one at a time. Return -EINVAL for invalid\ncombinations in amdgpu_gem_create_ioctl().\n\nv2: Rename helper from amdgpu_gem_domain_valid() to\n    amdgpu_gem_are_domains_valid() (Christian)\n\n(cherry picked from commit db39852d0c39843cb02048dfb47e4b8c703e9080)","published":"2026-08-26T14:37:14.572Z","modified":"2026-08-28T03:47:29.032294018Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.266"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/220aa2589d7321fb68d2e8597862711b5f22ae0b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/493355096e397f9217b41c8574ed2784c7351443"},{"type":"WEB","url":"https://git.kernel.org/stable/c/584e3d47736fe2e7184ef3fc16b00b41485f96c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c73485af7ad9c3ae592db3481f370bc07705391"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e9d136ad74df4edec67e502ce267597064d8f86"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66133fc05c3af002f45de8a71b833c026ccbfba6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/80f0b53860d02577709d69a312a29ca674b9297c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce5da474c3ddf7cccec5dce6aa4296297dd7caff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80541.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80541"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-28T03:47:29.032294018Z"}}
