However, build_skb() can fail under memory pressure.\nThis results in a kernel panic because the skb to reserve is NULL.\n\nAdd a check in case build_skb() failed to allocate and return NULL.\n\nThe NULL return is handled correctly in callers to qede_build_skb().","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-476"],"references":["https://git.kernel.org/stable/c/034a92c6a81048128fc7b18d278d52438a13902a","https://git.kernel.org/stable/c/4e910dbe36508654a896d5735b318c0b88172570","https://git.kernel.org/stable/c/8928239e5e2e460d95b8a0b89f61671625e7ece0","https://git.kernel.org/stable/c/9648adb1b3ece55c657d3a4f52bfee663b710dfe","https://git.kernel.org/stable/c/b2d6b3db9d1cf80908964036dbe1c52a86b1afb1"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49084","score":0.00672,"percentile":0.5208,"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).
