In the case where\ni is 32 or more this can lead to an overflow.  Avoid this by shifting\nusing the BIT_ULL macro instead.","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-190"],"references":["https://git.kernel.org/stable/c/08245672cdc6505550d1a5020603b0a8d4a6dcc7","https://git.kernel.org/stable/c/14cc13e433e1067557435b1adbf05608d7d47a93","https://git.kernel.org/stable/c/a4d01fb87ece45d4164fd725890211ccf9a307a9","https://git.kernel.org/stable/c/f84c9b72fb200633774704d8020f769c88a4b249","https://git.kernel.org/stable/c/fbf7b0e4cef3b5470b610f14fb9faa5ee7f63954"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2022-49748","score":0.00194,"percentile":0.09109,"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).
