Since if_id can be any 16-bit value (0-65535) but the ports\narray is only allocated with sw_attr.num_ifs elements, this can lead to\nan out-of-bounds read potentially.\n\nAdd a bounds check before accessing the array, consistent with the\nexisting validation in dpaa2_switch_rx().","state":0,"publishedAt":"2026-02-14T16:27:11.463+00:00","modifiedAt":"2026-10-19T18:25:34.438+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/net/ethernet/freescale/dpaa2/dpaa2-switch.c\"\n ],\n \"versions\": [\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"77611cab5bdfff7a070ae574bbfba20a1de99d1b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"34b56c16efd61325d80bf1d780d0e176be662f59\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"f89e33c9c37f0001b730e23b3b05ab7b1ecface2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"2447edc367800ba914acf7ddd5d250416b45fb31\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"1b381a638e1851d8cfdfe08ed9cdbec5295b18c9\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"24ab724f8a4661b2dc8e696b41df93bdc108f7a1\",\n \"lessThan\": \"31a7a0bbeb006bac2d9c81a2874825025214b6d8\",\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/net/ethernet/freescale/dpaa2/dpaa2-switch.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.15\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.15\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.200\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.163\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.124\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.70\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.10\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19\",\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:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/77611cab5bdfff7a070ae574bbfba20a1de99d1b","https://git.kernel.org/stable/c/34b56c16efd61325d80bf1d780d0e176be662f59","https://git.kernel.org/stable/c/f89e33c9c37f0001b730e23b3b05ab7b1ecface2","https://git.kernel.org/stable/c/2447edc367800ba914acf7ddd5d250416b45fb31","https://git.kernel.org/stable/c/1b381a638e1851d8cfdfe08ed9cdbec5295b18c9","https://git.kernel.org/stable/c/31a7a0bbeb006bac2d9c81a2874825025214b6d8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-23180","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-23180","identifiers":["CVE-2026-23180"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
