CVE-2026-46201 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import() When xe_dma_buf_init_obj() fails, the attachment from dma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before returning the error. Note: we cannot use goto out_err here because xe_dma_buf_init_obj() already frees bo on failure, and out_err would double-free it. (cherry picked from commit a828eb185aac41800df8eae4b60501ccc0dbbe51)
A vulnerability exists in the Linux kernel's Direct Rendering Manager (DRM) for Intel GPUs, specifically within the XE driver. The issue arises in the 'xe_gem_prime_import()' function, where a failure in 'xe_dma_buf_init_obj()' does not properly detach a DMA buffer attachment, leading to a resource leak. This vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The fixed version is included in the Linux kernel stable tree.
