If\ni2c_smbus_read_i2c_block_data_or_emulated() returns a value less than\nthe size of the buffer, uninitialized bytes are retained in the buffer\nand later the buffer is passed on to IIO buffers, potentially leaking\nmemory to userspace.\n\nFix this by adding checks whether the return value of the function is\nequal to the size of the buffer and subsequently if the value is\nlesser than zero to distinguish from a returned error code.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/12848f4ded022963944c063e09a192549a4dad1e","https://git.kernel.org/stable/c/3d57672119525c59ed73ea21accb001ccbcd6cfd","https://git.kernel.org/stable/c/8cf346074533356d67a6a6a43a192328ad341f11","https://git.kernel.org/stable/c/9f920550abacedc7fc3163dea65ac2a7d0b0765d","https://git.kernel.org/stable/c/a9a00d727b7bbc5e913a919530a9dd468935bf95"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72481","score":0.0022,"percentile":0.12523,"date":"2026-10-31"},"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).
