{"id":"CVE-2025-38529","summary":"comedi: aio_iiro_16: Fix bit shift out of bounds","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: aio_iiro_16: Fix bit shift out of bounds\n\nWhen checking for a supported IRQ number, the following test is used:\n\n\tif ((1 \u003c\u003c it-\u003eoptions[1]) & 0xdcfc) {\n\nHowever, `it-\u003eoptions[i]` is an unchecked `int` value from userspace, so\nthe shift amount could be negative or out of bounds.  Fix the test by\nrequiring `it-\u003eoptions[1]` to be within bounds before proceeding with\nthe original test.  Valid `it-\u003eoptions[1]` values that select the IRQ\nwill be in the range [1,15]. The value 0 explicitly disables the use of\ninterrupts.","modified":"2026-04-02T12:48:01.256333Z","published":"2025-08-16T11:12:22.447Z","related":["SUSE-SU-2025:03272-1","SUSE-SU-2025:03290-1","SUSE-SU-2025:03301-1","SUSE-SU-2025:03382-1","SUSE-SU-2025:03602-1","SUSE-SU-2025:03633-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20653-1","SUSE-SU-2025:20669-1","SUSE-SU-2025:20739-1","SUSE-SU-2025:20756-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","openSUSE-SU-2026:20287-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38529.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/43ddd82e6a91913cea1c078e782afd8de60c3a53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ac7c60439236fb691b8c7987390e2327bbf18fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66acb1586737a22dd7b78abc63213b1bcaa100e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/955e8835855fed8e87f7d8c8075564a1746c1b4c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a88692245c315bf8e225f205297a6f4b13d6856a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c593215385f0c0163015cca4512ed3ff42875d19"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0f3c0867d7d231c70984f05c97752caacd0daba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff30dd3f15f443d2a0085b12ec2cc95d44f35fa7"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38529.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38529"},{"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":"ad7a370c8be47247f68f7187cc82f4f25a347116"},{"fixed":"a88692245c315bf8e225f205297a6f4b13d6856a"},{"fixed":"5ac7c60439236fb691b8c7987390e2327bbf18fa"},{"fixed":"c593215385f0c0163015cca4512ed3ff42875d19"},{"fixed":"ff30dd3f15f443d2a0085b12ec2cc95d44f35fa7"},{"fixed":"955e8835855fed8e87f7d8c8075564a1746c1b4c"},{"fixed":"e0f3c0867d7d231c70984f05c97752caacd0daba"},{"fixed":"43ddd82e6a91913cea1c078e782afd8de60c3a53"},{"fixed":"66acb1586737a22dd7b78abc63213b1bcaa100e4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38529.json"}}],"schema_version":"1.7.5"}
