Currently\n'name' size is 16, but the first '%s' specifier may already need at\nleast 16 characters, since 'bnad->netdev->name' is used there.\n\nFor '%d' specifiers, assume that they require:\n * 1 char for 'tx_id + tx_info->tcb[i]->id' sum, BNAD_MAX_TXQ_PER_TX is 8\n * 2 chars for 'rx_id + rx_info->rx_ctrl[i].ccb->id', BNAD_MAX_RXP_PER_RX\n   is 16\n\nAnd replace sprintf with snprintf.\n\nDetected using the static analysis tool - Svace.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-787"],"references":["https://git.kernel.org/stable/c/6ce46045f9b90d952602e2c0b8886cfadf860bf1","https://git.kernel.org/stable/c/6d20c4044ab4d0e6a99aa35853e66f0aed5589e3","https://git.kernel.org/stable/c/ab748dd10d8742561f2980fea08ffb4f0cacfdef","https://git.kernel.org/stable/c/b0ff0cd0847b03c0a0abe20cfa900eabcfcb9e43","https://git.kernel.org/stable/c/c90b1cd7758fd4839909e838ae195d19f8065d76"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-43839","score":0.00254,"percentile":0.16991,"date":"2026-11-01"},"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).
