Sign extend its arguments properly to avoid kernel panic.\nThis is done by adding a new emit_abi_ext() helper. The emit_abi_ext()\nhelper performs extension in place meaning a value already store in the\ntarget register (Note: this is different from the existing sign_extend()\nhelper and thus we can't reuse it).","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":[],"references":["https://git.kernel.org/stable/c/0d666db731e95890e0eda7ea61bc925fd2be90c6","https://git.kernel.org/stable/c/321993a874f571a94b5a596f1132f798c663b56e","https://git.kernel.org/stable/c/3f5a238f24d7b75f9efe324d3539ad388f58536e","https://git.kernel.org/stable/c/fd43edf357a3a1f5ed1c4bf450b60001c9091c39"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-71129","score":0.00136,"percentile":0.0303,"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).
