{"id":"CVE-2024-26778","summary":"fbdev: savage: Error out if pixclock equals zero","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: savage: 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\nAlthough pixclock is checked in savagefb_decode_var(), but it is not\nchecked properly in savagefb_probe(). Fix this by checking whether\npixclock is zero in the function savagefb_check_var() before\ninfo-\u003evar.pixclock is used as the divisor.\n\nThis is similar to CVE-2022-3061 in i740fb which was fixed by\ncommit 15cf0b8.","modified":"2026-03-20T12:35:12.939005Z","published":"2024-04-03T17:01:08.782Z","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-2024-26778.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04e5eac8f3ab2ff52fa191c187a46d4fdbc1e288"},{"type":"WEB","url":"https://git.kernel.org/stable/c/070398d32c5f3ab0e890374904ad94551c76aec4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/224453de8505aede1890f007be973925a3edf6a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/512ee6d6041e007ef5bf200c6e388e172a2c5b24"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84dce0f6a4cc5b7bfd7242ef9290db8ac1dd77ff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c54acf33e5adaad6374bf3ec1e3aff0591cc8e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a9ca4e80d23474f90841251f4ac0d941fa337a01"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc3c2e58d73b28b9a8789fca84778ee165a72d13"},{"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-2024-26778.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26778"},{"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":"224453de8505aede1890f007be973925a3edf6a1"},{"fixed":"84dce0f6a4cc5b7bfd7242ef9290db8ac1dd77ff"},{"fixed":"512ee6d6041e007ef5bf200c6e388e172a2c5b24"},{"fixed":"8c54acf33e5adaad6374bf3ec1e3aff0591cc8e1"},{"fixed":"070398d32c5f3ab0e890374904ad94551c76aec4"},{"fixed":"bc3c2e58d73b28b9a8789fca84778ee165a72d13"},{"fixed":"a9ca4e80d23474f90841251f4ac0d941fa337a01"},{"fixed":"04e5eac8f3ab2ff52fa191c187a46d4fdbc1e288"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-26778.json"}}],"schema_version":"1.7.5"}
