hwmon: (asus_atk0110) Check package count before accessing element

Noroxi assessment

Priority: Monitor (action score 33/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2a137124664aad1e36d8d74e8e2207365a04737f, 459b0a0439ea65b2b612aa572eb62a2e26d05618, 76392d35c8df471b288cfc6536bd092b3c8ee2cf.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2a137124664aad1e36d8d74e8e2207365a04737f, 459b0a0439ea65b2b612aa572eb62a2e26d05618, 76392d35c8df471b288cfc6536bd092b3c8ee2cf or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
