If a second operation is\ninitiated immediately after, it overwrites the shared context in the\nDMA area.\n\nWhen the first operation's completion is processed later, it reads\nthis corrupted context, leading to unexpected behavior and incorrect\nresults.\n\nThis commit fixes the race by introducing a private context within\neach IPSec offload object. The shared ASO context is now copied to\nthis private context while the ASO spinlock is held. Subsequent\nprocessing uses this saved, per-object context, ensuring its integrity\nis maintained.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/2c6a5be0aee5a44066f68a332c30650900e32ad4","https://git.kernel.org/stable/c/6834d196107d5267dcad31b44211da7698e8f618","https://git.kernel.org/stable/c/99aaee927800ea00b441b607737f9f67b1899755","https://git.kernel.org/stable/c/99b36850d881e2d65912b2520a1c80d0fcc9429a","https://git.kernel.org/stable/c/c3db55dc0f3344b62da25b025a8396d78763b5fa"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-23441","score":0.00092,"percentile":0.00495,"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).
