How to fix?

There is no fixed version for RHEL:10 kernel-debug-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel package and not the kernel-debug-devel package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
