CVE-2026-98608: drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 1586ee6107acab3b14510ac6af939f1253269df8, 477bc3068fc3777b9d8ffd79e265b0dfdf2d3a6b, 574ae9fa5fd3658bee23cb544fe5a0d1d750016a; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1586ee6107acab3b14510ac6af939f1253269df8, 477bc3068fc3777b9d8ffd79e265b0dfdf2d3a6b, 574ae9fa5fd3658bee23cb544fe5a0d1d750016a; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl() virtio_gpu_resource_create_ioctl() calls drm_gem_object_release() on the drm_gem_handle_create() error path instead of dropping the reference it owns, so obj->funcs->free() never runs and the virtio_gpu_object, its pages and sg table, the resource id and the host-side resource are leaked. Use drm_gem_object_put() instead.
