It is a value in\nthe u8 range.  The final length we pass to av7110_ipack_instant_repack()\nis \"len - (buf[4] + 1) - 4\" so add a check to ensure that the length is\nnot negative.  It's not clear that passing a negative len value does\nanything bad necessarily, but it's not best practice.\n\nWith the new bounds checking the \"if (!len)\" condition is no longer\npossible or required so remove that.","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:N/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/423350af9e27f005611bd881b1df2cab66de943d","https://git.kernel.org/stable/c/620b983589e0223876bf1463b01100a9c67b56ba","https://git.kernel.org/stable/c/6606e2404ee9e20a3ae5b42fc3660d41b739ed3e","https://git.kernel.org/stable/c/6680af5be9f08d830567e9118f76d3e64684db8f","https://git.kernel.org/stable/c/77eeb4732135c18c2fdfab80839645b393f3e774"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:18:08.089039631+00:00"},"epss":{"cve":"CVE-2023-54284","score":0.00157,"percentile":0.04837,"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).
