CVE-2026-98608

A flaw was found in the Linux kernel's VirtIO GPU graphics processing unit driver. When handling resource creation requests, an improper error-handling path fails to release acquired object references upon failure, causing memory and system resources to leak. A local user could exploit this flaw ...

CVE-2026-98609

A flaw was found in the Linux kernel's VirtIO GPU driver. When graphics buffer handle creation fails, the driver improperly handles object references, preventing cleanup functions from freeing allocated memory and host resources. A local attacker could exploit this vulnerability to trigger a...

CVE-2026-98607

A flaw was found in the Linux kernel's VirtIO GPU driver. This vulnerability allows a local user to cause a denial of service DoS through memory and resource exhaustion. When errors occur during the creation of graphical resources, the driver fails to properly release object references, preventin...

CVE-2026-98606

A flaw was found in the Linux kernel's VirtIO GPU driver. During error handling when creating video memory resources, the driver deallocates memory without properly releasing the object from kernel memory tracking structures. A local user can exploit this vulnerability to trigger a use-after-free...

CVE-2026-98509

A flaw was found in the Linux kernel's virtio graphics processing unit virtio-gpu driver. A local user can cause a Denial of Service DoS by triggering a kernel memory leak during graphics command buffer processing. When invalid submission parameters are provided, the driver's error-handling path...

CVE-2026-98508

A flaw was found in the Linux kernel's VirtIO GPU driver. This flaw allows a local user to cause a denial of service DoS by triggering a kernel crash. Under memory pressure, the driver fails to verify whether fence memory allocation succeeds during graphics command submission, leading to an...
