{"apiVersion":"1.0","identifier":"CVE-2026-80593","description":"In the Linux kernel, the following vulnerability has been resolved: hwmon: (asus_atk0110) Check package count before accessing element atk_ec_present() walks the management group package returned by the GGRP ACPI method and, for each sub-package, reads its first element: id = &obj->package.elements[0]; if (id->type != ACPI_TYPE_INTEGER) without checking that the sub-package is non-empty. ACPICA allocates the element array with exactly package.count entries, so for a sub-package with a zero count this reads past the allocation. The sibling function atk_debugfs_ggrp_open() performs the same access but skips empty packages with a package.count check first. Add the same check to atk_ec_present() so a malformed firmware package cannot trigger an out-of-bounds read.","publishedAt":"2026-08-28T08:16:42","lastModifiedAt":"2026-08-28T08:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80593","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00176,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80593","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80593","en":"https://www.redsauce.net/en/cves/CVE-2026-80593","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80593","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80593","de":"https://www.redsauce.net/de/cves/CVE-2026-80593","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80593","el":"https://www.redsauce.net/el/cves/CVE-2026-80593"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80593"}}
