{"id":"CVE-2026-98876","summary":"host1x: bus: Fix missing ops null check in error teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhost1x: bus: Fix missing ops null check in error teardown\n\nIn host1x_device_init(), the error teardown paths do not check\nclient-\u003eops before dereferencing it, unlike the forward init paths\nwhich correctly guard with 'client-\u003eops &&'. This can result in a\nNULL pointer dereference if client-\u003eops is NULL.\n\nFix by adding the missing client-\u003eops check in both the teardown\nand teardown_late labels.","modified":"2026-11-04T14:27:18.514107686Z","published":"2026-10-23T11:37:21.776Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98876.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/29375e071ea201fe97bafe1d2ad9d9f30311abfb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/62851e7b0e55de6fe08da08bc41fd587fbcb0e9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71d25f668bc5c0f36ea843462e12307dea45aaa3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74bd1f05d9ba2d6672d30ccafe80a38104c1f73f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d8d5b6e02fc281dea33d6b0b0fadaccea56f2067"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1fa6c936fa9de80ae446ba5e76e227e991b8e56"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98876.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98876"},{"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":"8f7da1578e90bf1af30269dc6dd8806c96e9c683"},{"fixed":"d8d5b6e02fc281dea33d6b0b0fadaccea56f2067"},{"fixed":"f1fa6c936fa9de80ae446ba5e76e227e991b8e56"},{"fixed":"74bd1f05d9ba2d6672d30ccafe80a38104c1f73f"},{"fixed":"62851e7b0e55de6fe08da08bc41fd587fbcb0e9b"},{"fixed":"29375e071ea201fe97bafe1d2ad9d9f30311abfb"},{"fixed":"71d25f668bc5c0f36ea843462e12307dea45aaa3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98876.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.16.0"},{"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":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98876.json"}}],"schema_version":"1.9.2"}
