{"id":"CVE-2024-44931","summary":"gpio: prevent potential speculation leaks in gpio_device_get_desc()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: prevent potential speculation leaks in gpio_device_get_desc()\n\nUserspace may trigger a speculative read of an address outside the gpio\ndescriptor array.\nUsers can do that by calling gpio_ioctl() with an offset out of range.\nOffset is copied from user and then used as an array index to get\nthe gpio descriptor without sanitization in gpio_device_get_desc().\n\nThis change ensures that the offset is sanitized by using\narray_index_nospec() to mitigate any possibility of speculative\ninformation leaks.\n\nThis bug was discovered and resolved using Coverity Static Analysis\nSecurity Testing (SAST) by Synopsys, Inc.","modified":"2026-04-02T12:18:31.576522Z","published":"2024-08-26T10:11:21.425Z","related":["MGASA-2024-0309","MGASA-2024-0310","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3383-1","SUSE-SU-2024:3983-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:4100-1","SUSE-SU-2024:4364-1","SUSE-SU-2025:0034-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/44xxx/CVE-2024-44931.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/18504710442671b02d00e6db9804a0ad26c5a479"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1b955f786a4bcde8c0ccb2b7d519def2acb6f3cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/672c19165fc96dfad531a5458e0b3cdab414aae4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ae2d8e75b741dbcb0da374753f972410e83b5f3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d682e89c44bd5819b01f3fbb45a8e3681a4b6d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c65ab97efcd438cb4e9f299400f2ea55251f3a67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d776c0486b03a5c4afca65b8ff44573592bf93bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d795848ecce24a75dfd46481aee066ae6fe39775"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/44xxx/CVE-2024-44931.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-44931"},{"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":"521a2ad6f862a28e2e43cb3e254a26bf0f9452e9"},{"fixed":"18504710442671b02d00e6db9804a0ad26c5a479"},{"fixed":"9ae2d8e75b741dbcb0da374753f972410e83b5f3"},{"fixed":"9d682e89c44bd5819b01f3fbb45a8e3681a4b6d0"},{"fixed":"c65ab97efcd438cb4e9f299400f2ea55251f3a67"},{"fixed":"672c19165fc96dfad531a5458e0b3cdab414aae4"},{"fixed":"1b955f786a4bcde8c0ccb2b7d519def2acb6f3cc"},{"fixed":"d776c0486b03a5c4afca65b8ff44573592bf93bb"},{"fixed":"d795848ecce24a75dfd46481aee066ae6fe39775"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-44931.json"}}],"schema_version":"1.7.5"}
