{"id":"CVE-2025-39954","summary":"clk: sunxi-ng: mp: Fix dual-divider clock rate readback","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nclk: sunxi-ng: mp: Fix dual-divider clock rate readback\n\nWhen dual-divider clock support was introduced, the P divider offset was\nleft out of the .recalc_rate readback function. This causes the clock\nrate to become bogus or even zero (possibly due to the P divider being\n1, leading to a divide-by-zero).\n\nFix this by incorporating the P divider offset into the calculation.","modified":"2026-04-02T12:48:13.549194Z","published":"2025-10-09T09:47:32.825Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39954.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/25fbbaf515acd13399589bd5ee6de5f35740cef2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/40108f69c372af3aea73e7829d6849a44638d662"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39954.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-39954"},{"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":"45717804b75eda8a76eacc04509ca4d68dd2caaf"},{"fixed":"40108f69c372af3aea73e7829d6849a44638d662"},{"fixed":"25fbbaf515acd13399589bd5ee6de5f35740cef2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-39954.json"}}],"schema_version":"1.7.5"}
