ACPICA allocates the\nelement array with exactly package.count entries, so for a sub-package\nwith a zero count this reads past the allocation.\n\nThe sibling function atk_debugfs_ggrp_open() performs the same access but\nskips empty packages with a package.count check first.  Add the same\ncheck to atk_ec_present() so a malformed firmware package cannot trigger\nan out-of-bounds read.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4},"cwes":[],"references":["https://git.kernel.org/stable/c/2a137124664aad1e36d8d74e8e2207365a04737f","https://git.kernel.org/stable/c/459b0a0439ea65b2b612aa572eb62a2e26d05618","https://git.kernel.org/stable/c/76392d35c8df471b288cfc6536bd092b3c8ee2cf","https://git.kernel.org/stable/c/768f20e7bb48d723b82cb142120263d0806fbeb8","https://git.kernel.org/stable/c/981a8a2e3773dc7e704943388a1fb97970b23275"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-80593","score":0.00196,"percentile":0.09174,"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).
