As a result, if we use\nget_random_bytes() to generate random bytes in the randbuf, the\nnull pointer dereference bug will happen.\n\nIn order to prevent allocation failure, this patch adds a separate\nfunction using buffer on kernel stack to generate random bytes in\nthe randbuf, which could prevent the kernel stack from overflow.","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/0eb2c0528e232b3c32cde9d5e1c9f80ba2996e49","https://git.kernel.org/stable/c/316f790ebcf94bdf59f794b7cdea4068dc676d4c","https://git.kernel.org/stable/c/3729ca9e48d19a03ae049e2bde510e161c2f3720","https://git.kernel.org/stable/c/7c15eb344b0d4d3468c9b2a7591ad2b859b29b88","https://git.kernel.org/stable/c/c37466406f075476c2702ecc01917928af871f3b"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-38575","score":0.00225,"percentile":0.13218,"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).
