{"id":"CVE-2024-42090","summary":"pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER\n\nIn create_pinctrl(), pinctrl_maps_mutex is acquired before calling\nadd_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()\ncalls pinctrl_free(). However, pinctrl_free() attempts to acquire\npinctrl_maps_mutex, which is already held by create_pinctrl(), leading to\na potential deadlock.\n\nThis patch resolves the issue by releasing pinctrl_maps_mutex before\ncalling pinctrl_free(), preventing the deadlock.\n\nThis bug was discovered and resolved using Coverity Static Analysis\nSecurity Testing (SAST) by Synopsys, Inc.","modified":"2026-03-20T12:38:40.792003Z","published":"2024-07-29T16:26:30.139Z","related":["ALSA-2024:7000","ALSA-2024:7001","SUSE-SU-2024:3189-1","SUSE-SU-2024:3190-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3251-1","SUSE-SU-2024:3252-1","SUSE-SU-2024:3383-1","SUSE-SU-2024:3483-1","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/2024/42xxx/CVE-2024-42090.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/01fe2f885f7813f8aed5d3704b384a97b1116a9e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4038c57bf61631219b31f1bd6e92106ec7f084dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/420ce1261907e5dbeda1e4daffd5b6c76f8188c0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48a7a7c9571c3e62f17012dd7f2063e926179ddd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/adec57ff8e66aee632f3dd1f93787c13d112b7a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b36efd2e3e22a329444b6b24fa48df6d20ae66e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b813e3fd102a959c5b208ed68afe27e0137a561b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e65a0dc2e85efb28e182aca50218e8a056d0ce04"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42090.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-42090"},{"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":"42fed7ba44e4e8c1fb27b28ad14490cb1daff3c7"},{"fixed":"e65a0dc2e85efb28e182aca50218e8a056d0ce04"},{"fixed":"420ce1261907e5dbeda1e4daffd5b6c76f8188c0"},{"fixed":"b813e3fd102a959c5b208ed68afe27e0137a561b"},{"fixed":"01fe2f885f7813f8aed5d3704b384a97b1116a9e"},{"fixed":"b36efd2e3e22a329444b6b24fa48df6d20ae66e6"},{"fixed":"4038c57bf61631219b31f1bd6e92106ec7f084dc"},{"fixed":"48a7a7c9571c3e62f17012dd7f2063e926179ddd"},{"fixed":"adec57ff8e66aee632f3dd1f93787c13d112b7a1"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-42090.json"}}],"schema_version":"1.7.5"}
