Which versions of Linux Kernel are affected by EUVD-2026-59751?

Linux kernel systems running VMware graphics virtualization contain a local privilege escalation vulnerability allowing standard users to gain administrative access, creating risk of data…. A patch is available.

How to fix or mitigate EUVD-2026-59751?

Within 24 hours, identify and catalog all systems running vulnerable Linux kernel versions (prior to 6.6.151, 6.12.103, 6.18.44, 7.1.8, or 7.2-rc6) and apply temporary restrictions on local user access pending patching. Within 7 days, deploy kernel patches from stable branches 6.6.151 or later across all systems following your change management procedures, prioritizing production virtual desktops and workstations. Within 30 days, verify complete remediation through automated kernel version scanning, confirm patch acceptance in baseline images, and document remediation status for audit compliance.

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: validate DRAW_PRIMITIVES header size before division

vmw_cmd_draw() computes

maxnum = (header->size - sizeof(cmd->body)) / sizeof(*decl);

where header->size is u32 and is taken straight from the user-supplied command stream. When header->size is less than sizeof(cmd->body) the unsigned subtraction wraps to nearly 4 GiB, producing a huge maxnum. Any user-controlled cmd->body.numVertexDecls then passes the bound and the loop dereferences decl[i] far past the end of the kernel command bounce buffer, producing an out-of-bounds read of kernel memory.

Reject undersized headers up front.

AnalysisAI

Out-of-bounds kernel memory read in the Linux kernel's vmwgfx DRM driver exposes systems running VMware-virtualized graphics to local privilege escalation or sensitive information disclosure. The flaw in vmw_cmd_draw() allows a low-privilege local user to supply a crafted DRAW_PRIMITIVES command stream header with an undersized size field, triggering unsigned integer underflow that produces a near-4 GiB loop bound and causes the kernel to dereference memory far beyond the allocated command bounce buffer. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires all of the following: (1) local interactive or shell access to a Linux system running as a VMware guest - the vmwgfx driver is only active on VMware SVGA II virtual hardware and is not present on bare-metal or non-VMware hypervisor configurations; (2) a low-privilege user account with read/write access to the DRM device node (/dev/dri/renderD* or /dev/dri/card*), which typically requires membership in the 'video' or 'render' group; (3) a kernel version from Linux 2.6.33 onwards with vmwgfx compiled in or loaded as a module, and not yet patched to 6.6.151, 6.12.103, 6.18.44, or 7.1.8. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 7.8 score with AV:L/AC:L/PR:L/UI:N reflects a locally exploitable flaw requiring only low-privilege user access - no special configuration complexity or user interaction is needed - meaning even a mid-sized municipal IT team in mielec running VMware-based virtual desktop infrastructure should treat this as a credible local escalation risk in their VM guest OS environments. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	A local user with a low-privilege shell on a Linux VM running on VMware infrastructure opens the DRM render device node and submits a crafted DRAW_PRIMITIVES command with header->size set to a value smaller than sizeof(cmd->body). The unsigned subtraction wraps to approximately 4 GiB, and with numVertexDecls set to a large attacker-controlled value, the kernel loop walks far beyond the allocated bounce buffer, reading arbitrary kernel memory that may contain credentials, cryptographic material, or pointers useful for further exploitation. …
Remediation	Upgrade to a fixed Linux kernel: stable releases 6.6.151, 6.12.103, 6.18.44, or 7.1.8 are available; pre-release users should target 7.2-rc6. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify and catalog all systems running vulnerable Linux kernel versions (prior to 6.6.151, 6.12.103, 6.18.44, 7.1.8, or 7.2-rc6) and apply temporary restrictions on local user access pending patching. …
