Without this patch, when the hardware writes a dummy\ndescriptor, iavf would not free the page allocated for the previous receive\nbuffer. This is an unlikely event but can still happen.\n\n[Jesse: massaged commit message]","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/2918419c06088f6709ceb543feb01752779ade4c","https://git.kernel.org/stable/c/6edb818732fc05fda495f5b3a749bd1cee01398b","https://git.kernel.org/stable/c/a9f49e0060301a9bfebeca76739158d0cf91cdf6","https://git.kernel.org/stable/c/c6af94324911ef0846af1a5ce5e049ca736db34b","https://git.kernel.org/stable/c/d88d59faf4e6f9cc4767664206afdb999b10ec77"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49583","score":0.00268,"percentile":0.19033,"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).
