CVE-2026-80593
8.4 · HIGHOverview
CVE-2026-80593 is a high-severity vulnerability. It was published on August 28, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
