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.","state":0,"publishedAt":"2026-08-28T06:48:20.816+00:00","modifiedAt":"2026-10-16T19:26:29.448+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/hwmon/asus_atk0110.c\"\n ],\n \"versions\": [\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"2a137124664aad1e36d8d74e8e2207365a04737f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"459b0a0439ea65b2b612aa572eb62a2e26d05618\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"768f20e7bb48d723b82cb142120263d0806fbeb8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"76392d35c8df471b288cfc6536bd092b3c8ee2cf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"981a8a2e3773dc7e704943388a1fb97970b23275\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"d8d4fa0c4f818e30b6f6737bdd989b7e2b511cae\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"b770fcfcdced569bcf7c6982aeea8c3d11a21c2b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9e6eba610c2eb68b05841a15ece1cf929c44aea3\",\n \"lessThan\": \"e2735b39f044bad7bf2017aef248935525bc0b97\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/hwmon/asus_atk0110.c\"\n ],\n \"versions\": [\n {\n \"version\": \"2.6.32\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"2.6.32\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.261\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.212\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.178\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.145\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.97\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.40\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.5\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/2a137124664aad1e36d8d74e8e2207365a04737f","https://git.kernel.org/stable/c/459b0a0439ea65b2b612aa572eb62a2e26d05618","https://git.kernel.org/stable/c/768f20e7bb48d723b82cb142120263d0806fbeb8","https://git.kernel.org/stable/c/76392d35c8df471b288cfc6536bd092b3c8ee2cf","https://git.kernel.org/stable/c/981a8a2e3773dc7e704943388a1fb97970b23275","https://git.kernel.org/stable/c/d8d4fa0c4f818e30b6f6737bdd989b7e2b511cae","https://git.kernel.org/stable/c/b770fcfcdced569bcf7c6982aeea8c3d11a21c2b","https://git.kernel.org/stable/c/e2735b39f044bad7bf2017aef248935525bc0b97"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-80593","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-80593","identifiers":["CVE-2026-80593"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
