{"id":"CVE-2026-43175","summary":"clk: rs9: Reserve 8 struct clk_hw slots for for 9FGV0841","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nclk: rs9: Reserve 8 struct clk_hw slots for for 9FGV0841\n\nThe 9FGV0841 has 8 outputs and registers 8 struct clk_hw, make sure\nthere are 8 slots for those newly registered clk_hw pointers, else\nthere is going to be out of bounds write when pointers 4..7 are set\ninto struct rs9_driver_data .clk_dif[4..7] field.\n\nSince there are other structure members past this struct clk_hw\npointer array, writing to .clk_dif[4..7] fields corrupts both\nthe struct rs9_driver_data content and data around it, sometimes\nwithout crashing the kernel. However, the kernel does surely\ncrash when the driver is unbound or during suspend.\n\nFix this, increase the struct clk_hw pointer array size to the\nmaximum output count of 9FGV0841, which is the biggest chip that\nis supported by this driver.","modified":"2026-06-18T03:54:33.715788598Z","published":"2026-05-06T11:27:49.496Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43175.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2f926875dffe2226ea26d129e16d9092cccd03aa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ec820fc28d0b8a0f3890d476b1976f20e8343cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82a34f344999d8029bcebf131028fa519140c7cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da86ca15d7389ee0b5df08e8f70c39354e6b8a4b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43175.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43175"},{"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":"f0e5e1800204b82af6d3e8ef03012ab4afc22358"},{"fixed":"2f926875dffe2226ea26d129e16d9092cccd03aa"},{"fixed":"da86ca15d7389ee0b5df08e8f70c39354e6b8a4b"},{"fixed":"82a34f344999d8029bcebf131028fa519140c7cc"},{"fixed":"5ec820fc28d0b8a0f3890d476b1976f20e8343cc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43175.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43175.json"}}],"schema_version":"1.7.5"}
