{"id":"CVE-2025-38482","summary":"comedi: das6402: Fix bit shift out of bounds","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: das6402: Fix bit shift out of bounds\n\nWhen checking for a supported IRQ number, the following test is used:\n\n\t/* IRQs 2,3,5,6,7, 10,11,15 are valid for \"enhanced\" mode */\n\tif ((1 \u003c\u003c it-\u003eoptions[1]) & 0x8cec) {\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":"2026-04-16T00:04:21.663491245Z","published":"2025-07-28T11:21:47.026Z","related":["SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38482.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3eab654f5d199ecd45403c6588cda63e491fcfca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4a3c18cde02e35aba87e0ad5672b3e1c72dda5a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/70f2b28b5243df557f51c054c20058ae207baaac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73f34d609397805c20d6b2ef5c07a4cbf7c4d63a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a3637027ceeba4ca5e500b23cb7d24c25592513"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a15e9c175f783298c4ee48146be6841335400406"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a18a42e77545afcacd6a2b8d9fc16191b87454df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de8da1063cce9234d55c8270d9bdf4cf84411c80"},{"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-2025-38482.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38482"},{"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":"79e5e6addbb18bf56075f0ff552094a28636dd03"},{"fixed":"a15e9c175f783298c4ee48146be6841335400406"},{"fixed":"de8da1063cce9234d55c8270d9bdf4cf84411c80"},{"fixed":"73f34d609397805c20d6b2ef5c07a4cbf7c4d63a"},{"fixed":"a18a42e77545afcacd6a2b8d9fc16191b87454df"},{"fixed":"8a3637027ceeba4ca5e500b23cb7d24c25592513"},{"fixed":"3eab654f5d199ecd45403c6588cda63e491fcfca"},{"fixed":"4a3c18cde02e35aba87e0ad5672b3e1c72dda5a4"},{"fixed":"70f2b28b5243df557f51c054c20058ae207baaac"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38482.json"}}],"schema_version":"1.7.5"}
