The mask 0x0f allows values 0-15, but\nthe array size of usb_if->dev[] is only 2. Values 2-15 cause heap\nout-of-bounds read, eventually causing kernel panic in the IRQ context.\n\nAdd bounds checking for ctrl_idx before the array access in both\npcan_usb_pro_handle_canmsg() and pcan_usb_pro_handle_error().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0149fdb50a30944827acf9600a2cc44de0325a7f","https://git.kernel.org/stable/c/0c9268457bd6e4058fe55b4db01b16661c2eacf5","https://git.kernel.org/stable/c/18b1a868a2cda66fb438007ba47ce5f2484db381","https://git.kernel.org/stable/c/1acab790b7cecd4e144d1d18bdfe549e282f6b0b","https://git.kernel.org/stable/c/39132f166ca8ce00ae60d8a9068e06a60943cc4b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74457","score":0.00177,"percentile":0.07209,"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).
