{"id":"CVE-2026-98606","summary":"drm/virtio: release the GEM object on virtio_gpu_vram_create() errors","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/virtio: release the GEM object on virtio_gpu_vram_create() errors\n\nvirtio_gpu_vram_create() frees the object with a bare kfree(vram) on\nboth error paths after drm_gem_private_object_init() has run, and on the\nsecond one after drm_gem_create_mmap_offset() has linked obj-\u003evma_node\ninto the device's VMA offset manager. The freed object stays in that\ninterval tree, so a later lookup or insertion walks freed memory, and\nthe dma_resv and gpuva lock are never destroyed.\n\nCall drm_gem_object_release() before kfree() on both paths.","modified":"2026-10-20T02:30:36.540777403Z","published":"2026-10-18T15:19:20.639Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98606.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/036d28db1818af2f9d80db771f5405da84d7732d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/03bdbf182082694ab2add620d85f1a8b8f51bbbc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5118b5fdf1eb9922a0cdd2afd25252081e2d4302"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c2cb3dd1447752b73d4f44d6b7434bc5259bfec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c8deb77d05bcc8f79e255f669d82ec6ce91be12"},{"type":"WEB","url":"https://git.kernel.org/stable/c/977c2934064969503cabf98b1135d202ff62822e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a9bb8f8fd5694185c2f71ff91869afb300aab392"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98606.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98606"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"16845c5d540929d2f4dc845f11fbbb238e69170a"},{"fixed":"977c2934064969503cabf98b1135d202ff62822e"},{"fixed":"5118b5fdf1eb9922a0cdd2afd25252081e2d4302"},{"fixed":"a9bb8f8fd5694185c2f71ff91869afb300aab392"},{"fixed":"03bdbf182082694ab2add620d85f1a8b8f51bbbc"},{"fixed":"5c2cb3dd1447752b73d4f44d6b7434bc5259bfec"},{"fixed":"7c8deb77d05bcc8f79e255f669d82ec6ce91be12"},{"fixed":"036d28db1818af2f9d80db771f5405da84d7732d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98606.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98606.json"}}],"schema_version":"1.9.0"}
