This buffer was not scrubbed and\nthus could lead to expose of unwanted data. When the buffer is used\nexplicitly scrub it at the end of the code block to avoid exposure of\nmaybe sensitive data.\n\nIn a similar way the function gcm_aes_crypt() hat an error path where\nthe CPACF param block was not scrubbed. Instead of return early now\nthese error paths go to end of function where explicit scrubbing is\ndone. Similar with the buffers which are part of the gcm_sg_walk\nstructs from the variables gw_in and gw_out.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/11eca05d2062032e1f07d56be58ed0b99f4b1d63","https://git.kernel.org/stable/c/538f00558db9a66aeff20c36f43692c178a0e0eb","https://git.kernel.org/stable/c/6ab772d675a885c3119bf0e79ea9e84756d7657a","https://git.kernel.org/stable/c/8b7c3b6914f19caf648d05726a86af6326d3c2c6","https://git.kernel.org/stable/c/8b90a47c4fba27bb4f2f086611742493629e9696"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97592","score":0.0021,"percentile":0.11158,"date":"2026-10-25"},"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).
