This could lead to an oops. The fix for NULL\npointer dereference in __unix_needs_revalidation shows this is at\nleast possible for af_unix sockets. While the fix for af_unix sockets\napplies for newer mediation this is still the fall back path for older\naf_unix mediation and other sockets, so ensure it is covered.","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/00b67657535dfea56e84d11492f5c0f61d0af297","https://git.kernel.org/stable/c/0dc19bca22606f7a61d5988408f74e3ae0ef3486","https://git.kernel.org/stable/c/3852eb9a0392eb435c03dcb47d581bcfe6a9a95b","https://git.kernel.org/stable/c/5121b7283f1c46e4c06b88b1dda7b064429d77de","https://git.kernel.org/stable/c/68538ec34fcb4194c7961dc4eca6f5537fec8067"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45848","score":0.0016,"percentile":0.05213,"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).
