{"id":"CVE-2026-98676","summary":"iio: adc: ade9000: fix NULL pointer dereference in clkout registration","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: adc: ade9000: fix NULL pointer dereference in clkout registration\n\nade9000_setup_clkout() passes NULL as the register address when\nregistering a divider clock. During clock registration, the common\nclock framework calls clk_divider_recalc_rate(), which dereferences\nthe address through readl(). As a result, probing an ADE9000 configured\nas a clock provider with an external input clock crashes.\n\nCLKOUT passes CLKIN through without changing its rate. Register it as\na 1:1 fixed-factor clock, which does not require register access.\n\nThis change does not affect the configuration using the internal clock,\nfor which the driver does not register a clock provider.","modified":"2026-10-19T02:47:07.150636936Z","published":"2026-10-18T15:45:31.286Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98676.json"},"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/134aa31a8d4e71f6ab1d155ad7b4502508832f72"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49ee1c6a3ebda6b7de06b2961b0e09c1c3fe536a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2400175228fbc10b29c49a7b5f70a7e80d144dd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98676.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98676"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"81de7b4619fc3682a3bedaa7e8d6b2d67ab4e10a"},{"fixed":"d2400175228fbc10b29c49a7b5f70a7e80d144dd"},{"fixed":"134aa31a8d4e71f6ab1d155ad7b4502508832f72"},{"fixed":"49ee1c6a3ebda6b7de06b2961b0e09c1c3fe536a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98676.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98676.json"}}],"schema_version":"1.9.0"}
