{"id":"CVE-2026-52904","summary":"drm/nouveau: fix nvkm_device leak on aperture removal failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/nouveau: fix nvkm_device leak on aperture removal failure\n\nWhen aperture_remove_conflicting_pci_devices() fails during probe, the\nerror path returns directly without unwinding the nvkm_device that was\njust allocated by nvkm_device_pci_new(). This leaks both the device\nwrapper and the pci_enable_device() reference taken inside it.\n\nJump to the existing fail_nvkm label so nvkm_device_del() runs and\nbalances both. The leak was introduced when the intermediate\nnvkm_device_del() between detection and aperture removal was dropped\nin favor of creating the pci device once.","modified":"2026-06-18T03:55:38.119628906Z","published":"2026-06-09T12:36:01.237Z","related":["openSUSE-SU-2026:11014-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52904.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4404d7d2dda4f3cc84a8fb6ac5417a2afc3b22d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5edd564ccb002ffc830e7818c1c4a992db774678"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6597ff1d8de3f583be169587efeafd8af134e138"},{"type":"WEB","url":"https://git.kernel.org/stable/c/843c0247cf21364e33bb5a8ffc9af57107d04d05"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52904.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52904"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c0bfe34330b5fafdbbc63a7124841711651b96b9"},{"fixed":"5edd564ccb002ffc830e7818c1c4a992db774678"},{"fixed":"4404d7d2dda4f3cc84a8fb6ac5417a2afc3b22d6"},{"fixed":"843c0247cf21364e33bb5a8ffc9af57107d04d05"},{"fixed":"6597ff1d8de3f583be169587efeafd8af134e138"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-52904.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-52904.json"}}],"schema_version":"1.7.5"}
