Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux 5.15

A NULL pointer dereference vulnerability was discovered in the vmwgfx driver, located in the file vmwgfxexecbuf.c within the GPU component of the Linux kernel. The vulnerability affects device files such as '/dev/dri/renderD128' or 'Dxxx'. This flaw allows a local attacker with a user account on...

CVE-2026-74445

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: reject DXBINDQUERY without a DX context vmwcmddxbindquery unconditionally dereferences swcontext-dxctxnode-ctx. Userspace can trigger a NULL pointer dereference from any render-node fd by submitting an execbuf with...

CVE-2026-74445

The CVE (CVE-2026-74445) affects the Linux kernel drm/vmwgfx path. The vulnerability arises when vmw_cmd_dx_bind_query() dereferences sw_context->dx_ctx_node->ctx if a DX_BIND_QUERY is submitted with dx_context_handle set to SVGA3D_INVALID_ID, allowing a NULL pointer dereference and kernel ...

CVE-2025-40111

CVE-2025-40111 affects the Linux kernel drm/vmwgfx component. The root cause is a use-after-free in the validation path: nodes stored in the validation duplicates hashtable originate from an arena allocator cleared at vmw_execbuf_process end, but one node escaped due to premature resource destruc...

kernel: vmwgfx: integer overflow in vmwgfx_execbuf.c

An integer overflow was found in the Linux kernel's vmwgfx driver. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, and able to issue an ioctl on the resulting file descriptor to crash the system, causing a denial of service...

kernel: vmwgfx: use-after-free in vmw_execbuf_tie_context

A use-after-free vulnerability was found in the Linux kernel's vmwgfx driver in vmwexecbuftiecontext. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, who can issue an ioctl on the resulting file descriptor, to crash the system, causin...
