A binary\ncarrying more than one PT_INTERP runs the case again and overwrites both\ninterpreter_name and interpreter. The previous name allocation leaks and\nso does the previous interpreter reference, along with the write denial\nopen_exec() took on it. The denial is never released, so the file stays\nunwritable for as long as the system runs.\n\nAn unprivileged caller reaches this with a crafted binary and repeats it\nat will. binfmt_elf stops at the first PT_INTERP. Do the same here.\n\nThe flaw dates back to the driver's introduction in the pre-git history\ntree introduced in v2.6.11 by 91808d6ebe39 (\"[PATCH] FRV: Add FDPIC ELF\nbinary format driver\").","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/21eaf5594a33d16343a011c752624099c30e918f","https://git.kernel.org/stable/c/3349ef6a366a61d631f6a263d12cea240957719d","https://git.kernel.org/stable/c/3c31397b0a75310217f1f2f3c7bdfd8af67aec4c","https://git.kernel.org/stable/c/69ecc199880bf7e8d06224c82dc411d18f9285f8","https://git.kernel.org/stable/c/849a7bd9d266e43a457db5c6b322600f916a2127"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68151","score":0.00184,"percentile":0.08057,"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).
