It calls ksmbd_krb5_authenticate to reinitialise\nsess->user but that function may return without doing so. If\nthat happens then smb2_sess_setup, which calls krb_authenticate,\nwill be accessing free'd memory when it later uses sess->user.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/1db2451de23e98bc864c6a6e52aa0d82c91cb325","https://git.kernel.org/stable/c/1e440d5b25b7efccb3defe542a73c51005799a5f","https://git.kernel.org/stable/c/6e30c0e10210c714f3d4453dc258d4abcc70364e","https://git.kernel.org/stable/c/b61f04d5d73c53d183019bafe22fb700a739bac5","https://git.kernel.org/stable/c/d5b554bc8d554ed6ddf443d3db2fad9f665cec10"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-37778","score":0.01141,"percentile":0.66424,"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).
