{"id":"CVE-2024-26777","summary":"fbdev: sis: Error out if pixclock equals zero","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: sis: Error out if pixclock equals zero\n\nThe userspace program could pass any values to the driver through\nioctl() interface. If the driver doesn't check the value of pixclock,\nit may cause divide-by-zero error.\n\nIn sisfb_check_var(), var-\u003epixclock is used as a divisor to caculate\ndrate before it is checked against zero. Fix this by checking it\nat the beginning.\n\nThis is similar to CVE-2022-3061 in i740fb which was fixed by\ncommit 15cf0b8.","modified":"2026-03-20T12:35:12.820520Z","published":"2024-04-03T17:01:02.935Z","related":["SUSE-SU-2024:1643-1","SUSE-SU-2024:1646-1","SUSE-SU-2024:1870-1","SUSE-SU-2024:2008-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2190-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26777.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1d11dd3ea5d039c7da089f309f39c4cd363b924b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6db07619d173765bd8622d63809cbfe361f04207"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84246c35ca34207114055a87552a1c4289c8fd7e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99f1abc34a6dde248d2219d64aa493c76bbdd9eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cd36da760bd1f78c63c7078407baf01dd724f313"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df6e2088c6f4cad539cf67cba2d6764461e798d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e421946be7d9bf545147bea8419ef8239cb7ca52"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f329523f6a65c3bbce913ad35473d83a319d5d99"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26777.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26777"},{"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":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2"},{"fixed":"84246c35ca34207114055a87552a1c4289c8fd7e"},{"fixed":"6db07619d173765bd8622d63809cbfe361f04207"},{"fixed":"cd36da760bd1f78c63c7078407baf01dd724f313"},{"fixed":"df6e2088c6f4cad539cf67cba2d6764461e798d1"},{"fixed":"f329523f6a65c3bbce913ad35473d83a319d5d99"},{"fixed":"99f1abc34a6dde248d2219d64aa493c76bbdd9eb"},{"fixed":"1d11dd3ea5d039c7da089f309f39c4cd363b924b"},{"fixed":"e421946be7d9bf545147bea8419ef8239cb7ca52"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-26777.json"}}],"schema_version":"1.7.5"}
