CVE-2026-68446Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Validate vmw_surface_metadata::array_size This field comes from userspace and should be validated against specific limits depending on which Shader Model (SM) is available. This vulnerability arises from insufficient validation of the `vmw_surface_metadata::array_size` field, which is supplied by userspace. An attacker could exploit this by providing a malformed `array_size` value, potentially leading to unexpected system behavior or a denial of service (DoS). This issue affects VMware vmwgfx virtual GPU guests. vmw_surface_metadata::array_size from userspace was not validated against shader model limits, potentially allowing out-of-bounds access. Systems not using vmwgfx are not affected. Red Hat severity…
