This may result in userspace attempting to submits a job before the register map is initialized. Address this by moving register initialization before host1x client registration. The Linux kernel CVE team has assigned CVE-2026-80883 to this issue. Affected and fixed versions =========================== Fixed in 6.6.145 with commit 6e22d5ad61cfa38aa53fab86a530113aff6a3619 Fixed in 6.12.97 with commit 5db37fd7710e74bc4df48bddab8f571d0bfc6769 Fixed in 6.18.40 with commit 40a2a91da02c434938f0ba53877984820800b5f0 Fixed in 7.1.5 with commit 3055292b8eed69553b389a609197a241df47e68e Fixed in 7.2 with commit c4ef5ba1131346159e31f4ef858525cf377380a6 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-80883 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/tegra/gr2d.c drivers/gpu/drm/tegra/gr3d.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/6e22d5ad61cfa38aa53fab86a530113aff6a3619 https://git.kernel.org/stable/c/5db37fd7710e74bc4df48bddab8f571d0bfc6769 https://git.kernel.org/stable/c/40a2a91da02c434938f0ba53877984820800b5f0 https://git.kernel.org/stable/c/3055292b8eed69553b389a609197a241df47e68e https://git.kernel.org/stable/c/c4ef5ba1131346159e31f4ef858525cf377380a6
