{"id":"CVE-2024-42290","summary":"irqchip/imx-irqsteer: Handle runtime power management correctly","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nirqchip/imx-irqsteer: Handle runtime power management correctly\n\nThe power domain is automatically activated from clk_prepare(). However, on\ncertain platforms like i.MX8QM and i.MX8QXP, the power-on handling invokes\nsleeping functions, which triggers the 'scheduling while atomic' bug in the\ncontext switch path during device probing:\n\n BUG: scheduling while atomic: kworker/u13:1/48/0x00000002\n Call trace:\n  __schedule_bug+0x54/0x6c\n  __schedule+0x7f0/0xa94\n  schedule+0x5c/0xc4\n  schedule_preempt_disabled+0x24/0x40\n  __mutex_lock.constprop.0+0x2c0/0x540\n  __mutex_lock_slowpath+0x14/0x20\n  mutex_lock+0x48/0x54\n  clk_prepare_lock+0x44/0xa0\n  clk_prepare+0x20/0x44\n  imx_irqsteer_resume+0x28/0xe0\n  pm_generic_runtime_resume+0x2c/0x44\n  __genpd_runtime_resume+0x30/0x80\n  genpd_runtime_resume+0xc8/0x2c0\n  __rpm_callback+0x48/0x1d8\n  rpm_callback+0x6c/0x78\n  rpm_resume+0x490/0x6b4\n  __pm_runtime_resume+0x50/0x94\n  irq_chip_pm_get+0x2c/0xa0\n  __irq_do_set_handler+0x178/0x24c\n  irq_set_chained_handler_and_data+0x60/0xa4\n  mxc_gpio_probe+0x160/0x4b0\n\nCure this by implementing the irq_bus_lock/sync_unlock() interrupt chip\ncallbacks and handle power management in them as they are invoked from\nnon-atomic context.\n\n[ tglx: Rewrote change log, added Fixes tag ]","modified":"2026-03-20T12:37:40.733854Z","published":"2024-08-17T09:08:59.848Z","related":["MGASA-2024-0309","MGASA-2024-0310","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3383-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42290.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/21bd3f9e7f924cd2fc892a484e7a50c7e1847565"},{"type":"WEB","url":"https://git.kernel.org/stable/c/33b1c47d1fc0b5f06a393bb915db85baacba18ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3a2884a44e5cda192df1b28e9925661f79f599a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/58c56735facb225a5c46fa4b8bbbe7f31d1cb894"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a590e8dea3df2639921f874d763be961dd74e8f9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8ae38f1dfe652779c7c613facbc257cec00ac44"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa1803401e1c360efe6342fb41d161cc51748a11"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html"},{"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-2024-42290.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-42290"},{"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":"0136afa08967f6e160b9b4e85a7a70e4180a8333"},{"fixed":"a590e8dea3df2639921f874d763be961dd74e8f9"},{"fixed":"3a2884a44e5cda192df1b28e9925661f79f599a1"},{"fixed":"fa1803401e1c360efe6342fb41d161cc51748a11"},{"fixed":"58c56735facb225a5c46fa4b8bbbe7f31d1cb894"},{"fixed":"21bd3f9e7f924cd2fc892a484e7a50c7e1847565"},{"fixed":"f8ae38f1dfe652779c7c613facbc257cec00ac44"},{"fixed":"33b1c47d1fc0b5f06a393bb915db85baacba18ea"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-42290.json"}}],"schema_version":"1.7.5"}
