If the whole packet is\nshorter than ETH_HLEN, eth_type_trans() reads the header past the end\nof the data instead.\n\nPull at least ETH_HLEN, and drop the packet if that fails, which also\ndrops packets too short to hold an Ethernet header.  This also checks\nthe return value of the pull, which was ignored.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0542d213253eec18785a24b603b28bd385dfe4a5","https://git.kernel.org/stable/c/089e58805c452e52179482b1025a8e309a57f801","https://git.kernel.org/stable/c/236a17caebcff31f75bec5ff4136bde2de944e40","https://git.kernel.org/stable/c/72d2f54367895d6e236b9857892e2e6b6036e067","https://git.kernel.org/stable/c/e2b721bc30f40ffa7ccc36a56d4e8990b8c0538e"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98375","score":0.00186,"percentile":0.08122,"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).
