{"id":"CVE-2026-72480","summary":"iio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling\n\nams_event_to_channel() may return a pointer past the end of\ndev-\u003echannels when no matching scan_index is found. This can lead\nto invalid memory access in ams_handle_event().\n\nAdd a bounds check in ams_event_to_channel() and return NULL when\nno channel is found. Also guard the caller to safely handle this\ncase.","modified":"2026-08-18T03:56:26.426607162Z","published":"2026-08-15T05:57:18.975Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72480.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/116d1f8805ae2daadbac89d24da4c0da50b9edae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d24f14e049fdd769146dda026496ed23b397ed9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c374d33f1338dbb5676919c5194caa9c5aa1631"},{"type":"WEB","url":"https://git.kernel.org/stable/c/947eb6f0a274f8b15a0248051a65b069effd5057"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94d158985b6ea011bdc26186f42d662a156da6cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ac3675bf875792dced45efbf47116719a7c097b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72480.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72480"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d5c70627a79455154f5f636096abe6fe57510605"},{"fixed":"116d1f8805ae2daadbac89d24da4c0da50b9edae"},{"fixed":"94d158985b6ea011bdc26186f42d662a156da6cb"},{"fixed":"1d24f14e049fdd769146dda026496ed23b397ed9"},{"fixed":"9ac3675bf875792dced45efbf47116719a7c097b"},{"fixed":"3c374d33f1338dbb5676919c5194caa9c5aa1631"},{"fixed":"947eb6f0a274f8b15a0248051a65b069effd5057"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72480.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.17.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72480.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
