If kmalloc() fails in add_interval(), it could\nresult in a null pointer being inserted into the linked list,\nleading to illegal memory access when sub_interval() is called\nnext.\n\nThis patch adds an error handling for the add_interval(). If\nadd_interval() returns an error, the function will return early\nwith the error code.","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/06b26e3099207c94b3d1be8565aedc6edc4f0a60","https://git.kernel.org/stable/c/289b58f8ff3198d091074a751d6b8f6827726f3e","https://git.kernel.org/stable/c/369bf6e241506583f4ee7593c53b92e5a9f271b4","https://git.kernel.org/stable/c/4a81f78caa53e0633cf311ca1526377d9bff7479","https://git.kernel.org/stable/c/5b60ed401b47897352c520bc724c85aa908dedcc"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-39920","score":0.00167,"percentile":0.05924,"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).
