When an I2C transfer fails, the uninitialized register\nvalue is converted and reported to userspace as a valid voltage or state\nof charge.  The polling worker can also replace the cached state of charge\nwith the bogus value and emit a spurious change event.\n\nPropagate read errors through the power supply get_property callback and\nkeep the last valid cached state of charge when polling fails.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/13fb0477da9b400071b9d518b24d6434c4965263","https://git.kernel.org/stable/c/2943a0edd4865ed744702ada647921c3981207f6","https://git.kernel.org/stable/c/659cc3d8d5ef246263873fce72c8cadeeed073cc","https://git.kernel.org/stable/c/bcdcbef9c5e69a1e79c6b9f6a3434da2f68724ed","https://git.kernel.org/stable/c/c7aa4c3708cc0d8487336f8281665eaea87130f6"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-89462","score":0.00168,"percentile":0.06155,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
